Electrical grade magnesia is mainly used in metallurgy, chemical industry, feed, environmental protection, medicine, fertilizer, building materials other industries. What are the preparation methods for electrical grade magnesia additives?
1, weigh magnesium oxide silicon dioxide;
2, mix in a mixing mixer to obtain a mixture;
3. Place the obtained mixture in a corundum sagger, calcine in a high-temperature furnace, then cool the material after the heat preservation;
4. Cool the obtained material to room temperature, add the boron compound, stir in another stirrer;
5. Place the obtained materials in a high-temperature furnace for calcination heat preservation;
6. Cool the obtained material to room temperature, pulverize it with a mechanical pulverizer, sieve through a screen to obtain an additive containing magnesium silicate.
