Three types of electrical-grade magnesium oxide powder
There are many electrical-grade magnesium oxide powder types, each suited to specific needs, environments and applications. Understanding these different options is crucial to choosing the right brand of electric heating tubes. Here are the three main types:
Low-temperature magnesium oxide powder
Low-temperature magnesium oxide powder is a compound with the chemical formula MGO. It is a fine white powder used in various applications due to its thermal properties, stability and alkalinity.
When we refer to “low temperature” in magnesium oxide powder, we usually mean that the powder is calcined or processed at a lower temperature, which affects its reactivity and purity.
The resulting magnesium oxide generally has a smaller crystal size and higher surface area at lower calcination temperatures. This can make low-temperature magnesium oxide powder more reactive, benefiting specific applications.
Such as refractory materials、environment、agriculture、medicine、chemical intermediates、electrical insulation、etc.
Medium-temperature magnesium oxide powder
Medium-temperature magnesium oxide powder is a variant of MgO. Medium-temperature magnesium oxide powder suits environments requiring a balance between reactivity and high-temperature resistance, making it ideal for all significant industrial environments. Chinese magnesium oxide powder can provide long-lasting performance from 800°C to 1500°C, ensuring the powder maintains a balance between reactivity and stability. It is suitable for applications where reactivity is not high or low.
One of the outstanding features of medium-temperature magnesium oxide powder is its excellent thermal conductivity and insulation. The balance between thermal conductivity and insulation allows medium-temperature magnesium oxide powders to be used when heat must be carefully managed – either by dispersion to prevent localized overheating or by controlling heat to maintain energy efficiency. This duality makes medium-temperature magnesium oxide powder a versatile material in the electronics and construction industries.
In addition, electrical-grade magnesium oxide powder also has the characteristics of economy and availability.
This feature balances performance and cost well, making it a widely used and economically viable option for many industrial applications.
High-temperature magnesium oxide powder
High-temperature magnesium oxide powder, or dead-burned magnesium oxide, is produced by calcining the raw material magnesite (magnesium carbonate) at temperatures typically above 1500°C.
High-temperature magnesium oxide powder is suitable for various challenging environments and ideal for industrial environments. These environments take advantage of high-temperature magnesium oxide powder’s high melting point, corrosion resistance and thermal shock resistance, making it a critical material for industrial processes operating in some of the most challenging conditions.
One of the outstanding features of high-temperature magnesium oxide powder is its extremely high melting point. The melting point of dead-burned magnesium oxide is around 2800°C, which is one of the highest melting points among ordinary refractory materials. This makes it particularly suitable for refractory linings of furnaces in the steel and cement industries, which can withstand prolonged exposure to extremely high temperatures.
In addition, high-temperature magnesium oxide powder also has excellent thermal shock resistance. This means it can withstand rapid temperature changes without cracking. This is beneficial for many industrial processes involving sudden heating or cooling.

Electrical grade magnesium oxide powder and traditional magnesium oxide powder
Electrical-grade magnesium oxide is a specialized form designed for high-performance electrical insulation. It has exceptionally high purity and specific physical properties, ensuring it functions effectively in electrical systems. Traditional magnesium oxide, while versatile, has a broader range of applications that only sometimes require such high levels of purity and performance consistency.
How to choose electrical grade magnesium oxide powder
Choosing the correct electrical grade magnesium oxide powder is critical for sustainable and cost-effective electric heating tubes. To get great results, you must consider the following key factors and features:
1.Working temperature
It is crucial to determine the maximum temperature that MGO powder can withstand. The choice of MGO depends on the maximum temperature used by your electric heating tube and the customer’s specific requirements.
For example, low-temperature magnesium oxide powder is suitable for working environments between 3°C and 700°C, medium-temperature magnesium oxide powder is suitable for working environments between 800°C and 1500°C, and high-temperature magnesium oxide powder is suitable for working environments between 800°C and 1500°C. The powder is suitable for working environments above 1500℃. Therefore, the use temperature is crucial to how to choose magnesium oxide powder.
2.Corrosion resistance
The chemical corrosion resistance of electrical-grade magnesium oxide powder is a crucial factor.
You should evaluate the chemical stability of your magnesium oxide powder in the presence of potential contaminants or reactive species you may encounter in your operating environment to ensure that the selected MGO retains its structural and chemical integrity when exposed to acids, bases, and solvent sex.
3. Electrical insulation ability
Determine electrical insulation needs, focusing on dielectric strength and resistivity. The selected magnesium oxide powder should have a high dielectric constant to prevent dielectric breakdown. It should be able to resist electric current to avoid short circuits and other electrical hazards.
4.Moisture resistance
Understanding the moisture-resistant properties of electrical-grade magnesium oxide powder is critical to making an informed decision. In electrical applications, the presence of moisture can cause the insulating properties of magnesium oxide to degrade, thereby increasing the risk of short circuits and electrical failures. Moisture can also cause chemical degradation of magnesium oxide, affecting its purity and reactive properties, which are critical for consistent performance.
Additionally, the moisture resistance of electrical-grade magnesium oxide powder prevents water-related degradation and maintains chemical stability, extending the life of the magnesium oxide powder. Magnesium oxide powder maintains its high resistivity and dielectric strength by resisting moisture absorption, which is critical for adequate insulation.
Evaluating these moisture-resistant properties will help you select a reliable, efficient electrical-grade magnesium oxide powder suitable for your work environment.
5.mechanical stability
The selected magnesium oxide powder should have a robust particle morphology that resists cracking, compaction, or segregation when subjected to physical stress, vibration, or impact, ensuring consistent application performance and service life.
6. Particle size and surface area considerations
Precisely defined particle size and surface area are critical to achieving the required packing density and surface coverage. Dense fillers may require fine powders, while larger particles may be preferred because of their less surface reactivity. The choice depends on the interactions between the MGO particles and their contact with other components.
7.Purity grade requirements
A high degree of purity is crucial for applications that cannot tolerate electrical or thermal impurities. The selected MgO powder should have minimal impurities to ensure high performance, particularly in high-precision electrical insulation.
8.Comply with standards and regulations
Magnesium oxide powder must comply with all relevant industry standards and regulations, including environmental, health and safety. Make sure the product is certified for use in your specific application, mainly if it is used in sensitive areas such as food processing or medical devices.
9.Supplier reliability and quality control
The ability to provide goods or services that consistently meet buyer requirements. Moreover, it maintains the high quality of electrical grade magnesium oxide powder.
When suppliers demonstrate high reliability and robust quality control, they will significantly contribute to the smooth operation and profitability of the procurement business. The relationship between a supplier and a buyer is strengthened when the supplier is viewed as a reliable part of the supply chain, able to provide products that meet the buyer’s quality and reliability standards.
These ten factors are crucial when choosing electrical-grade magnesium oxide powder. You can make an informed decision about your electric heating tube needs by evaluating these points.
