硼泥制备微晶玻璃的晶化行为

针对硼泥、铁尾矿和粉煤灰的成分特点,系统研究了在不同原料配比条件下微晶玻璃的析晶行为,深入探讨了利用硼泥、铁尾矿和粉煤灰制备矿渣微晶玻璃的原料配比对晶化行为的影响.结果表明:随着硼泥配入量的增加,微晶玻璃的初始析晶温度降低,矿渣微晶玻璃的主析晶相为钙铁辉石,当硼泥配入量为30%~40%时,矿渣微晶玻璃的晶体分布较为均匀,球晶有利于性能的提高.

Crystallization Behavior of Glass-Ceramics Prepared from Boron Mud

According to the characteristics of the composition of boron mud, ferrous tailing and fly ash as raw materials, the crystallization behavior of glass-ceramics in different mixture ratios was studied systematically. The results showed that, with the increasing boron mud the initial crystallizing temperature of such glass ceramics lowers, and the principal crystalline phase is hedenbergite. When the boron mud component comes to 30%-40% in mixture ratio, the crystal distribution become relatively uniform. Transforming the crystal form from branch to ball can improve the properties of glass ceramics.
