Influence of Waste Materials Containing Tungsten on Melting and Crystallization of Glass-ceramics
Influences of waste materials containing tungsten on melting and crystallization of glass-ceramics are discussed in this article.High temperature melting,nucleation and crystallization of glass-ceramics were explored by means of DTA,XRD and SEM.The high temperature melting performance of glass-ceramics ingredients can be effectively improved by mixing the right amount of waste materials containing tungsten.But the additive amount should be properly controlled,the mixing content of waste materials containing tungsten should be a range of 0.5 ~ 2.0 %.In the experiment of glass-ceramics ingredients system,the molten softening temperature of base glass powder reduced about 20℃ by adding 1% waste materials containing tungsten,and the nucleation temperature reduced about 15 ℃.The nucleation and crystallization performance of glass-ceramics mineral crystals can be promoted by mixing the right amount of waste materials containing tungsten.That is helpful to improve the quality of glass-ceramics products.
