工业固体废弃物成分对CaO-Al_(2)O_(3)-SiO_(2)体系微晶玻璃的影响

Effect of Industrial Solid Waste Component on CaO-Al_(2)O_(3)-SiO_(2) Glass-Ceramics

通过对大量文献进行整理,首次阐述了CaO、Al_(2)O_(3)、SiO_(2)含量较多的工业固体废弃物,根据成分不同分别从玻璃液高温熔融粘度、晶化程度、微晶玻璃物理性能三个方面对CaO-Al_(2)O_(3)-SiO_(2)体系微晶玻璃的制备及性能影响进行总结。结果表明:随着CaO含量的增多,玻璃液高温熔融粘度降低,晶化程度不断提高,微晶玻璃力学性能先升高后下降;随着Al_(2)O_(3)、SiO_(2)含量的增多,玻璃液高温熔融粘度升高,晶化程度不断降低,微晶玻璃力学性能先升高后下降。

For the first time,the industrial solid wastes with high content of CaO,Al_(2)O_(3),SiO_(2)are described in this paper by reviewing a large number of literatures.According to the different components,the preparation and properties of CaO-Al_(2)O_(3)-SiO_(2)glass-ceramics are summarized from three aspects,namely,the high-temperature melting viscosity of glass liquid,the degree of crystallization,and the physical properties of the glass-ceramics.The results show that with the increase of CaO content,the melting viscosity of glass decreases at high temperature,the degree of crystallization increases and the physical properties of glass-ceramics are strengthened constantly.With the increase of Al_(2)O_(3)and SiO_(2)contents,the melting viscosity of glass increase at high temperature,the degree of crystallization decrease,and the physical properties of glass-ceramics are strengthened constantly.
