以粉煤灰为基础的微晶玻璃的制备
Preparation of the glass-ceramics based on the flyash
摘要
Abstract
The preparation of the basic glass of the Na2O-CaO-SiO2 system with above 50wt% flyash content and TiO2/Fe2O3 as nucleation agent has been investigated by adopting conventional melt quenching technology.The nucleation and the crystallization temperatures are determined by using DTA.The phase and the microstructure of the glass-ceramics are investigated according to the results of the X-ray diffraction analysis and the SEM.The results show that,when introducing the flyash as main raw material,the glass of the Na2O-CaO-SiO2 system can be obtained;yellow color or black color glass-ceramics containing main crystal phases such as NaAlSiO4,Ca2Al2SiO7 etc.may be obtained by using two-stage heat-treatment method.The SEM photographs show that the micro-crystals in the glass-ceramic structure are lumpy shape and the glass is almost crystallized completely.关键词
