The difference between large crystalline fused magnesia and fused magnesia：
Large crystalline fused magnesia and fused magnesite are both magnesia refractory materials made from natural magnesite ore through high-temperature electric fusion, but there are some differences between them:
1. Crystal size: The crystal size of large crystal fused magnesia is larger, usually between tens of microns and hundreds of microns; while the crystal size of fused magnesite is smaller, usually between a few microns and tens of microns. .
2. Purity: The purity of large crystal fused magnesia is relatively high, and the magnesium oxide content is generally above 98%; while the purity of fused magnesite is relatively low, and the magnesium oxide content is usually between 95% and 98%.
3. Usage: Because large crystalline fused magnesia has high purity and good hydration resistance, it is mainly used to manufacture high-performance refractory materials, such as ladle linings, electric furnace linings, etc.; while fused magnesia is widely used in Common refractory materials, building materials, chemical industry and other fields.
In general, there are certain differences between large crystalline fused magnesite and fused magnesia in terms of crystal size, purity, and use. The choice of material should be determined based on specific usage requirements and working conditions.
