微钠电熔莫来石

玉发集团生产的微钠莫来石氧化钠含量小于0.1%，主要晶相为莫来石相。

The YUFA Group produces micro sodium mullite with a sodium oxide content of less than 0.1%, and the primary crystal phase is mullite.

氧化钠对于莫来石是一种有害杂质，它对莫来石起分解作用，增加非晶质相，弱化高温性能，阻碍莫来石相的生成，易生成低温熔融的玻璃相，从而降低莫来石的耐火度，玻璃相生成量随着钠含量的增加而增大。

Sodium oxide is a detrimental impurity for mullite as it decomposes mullite, increases amorphous phases, weakens high-temperature performance, hinders mullite formation, and easily creates low-temperature molten glass phases, thereby reducing mullite's refractory degree. The amount of generated glass phase rises with increasing sodium content.

微钠莫来石因氧化钠含量降低，其耐火度、体积密度、抗折强度、耐压强度、真密度、硬度等较普通莫来石均有明显提升。

Micro sodium mullite, with reduced sodium oxide content, exhibits significantly improved fire resistance, bulk density, flexural strength, compressive strength, true density, and hardness compared to regular mullite.
