The electric grade magnesium oxide powder used for electric oven, which is high temperature insulation and used in organic coating, includes the mixture. The mixture includes fused magnesia powder and inorganic material powder. On the surface of these powders, it has organic material layered.
The production method process of it includes follow steps:
- The preparation of fused magnesia powder.
- The preparation of the mixture.
- The addition of organic materials.
- The preparation of materials.
- The preparation of high temperature insulation magnesium oxide powder.
The electric grade magnesium oxide powder used for electric oven used for making electrical heating element. And then, the electrical heating element used in electric oven should satisfy two key conditions: high temperature resistance and humidity resistance. What’s more, this electrical heating element does not need to be annealed in 1050℃.
