Influence Of Different Silica Raw Materials On Na-Ca-Si Glass Properties

The most important materials of making glass is silica raw material, because it can provide SiO2 which is the mian component of glass. SiO2 is the carcass of glass, which can increase glass's viscosity and recede glass's propensity of devitrification, at same time, it can raise glass's chemical stability and thermal stability.The quality of silica raw material can produce an effect on glass's quality directly, silica raw materials's component, grain size and constancy impact the glass's quality. If silica raw materials's quality don't meet the glass's demand.it doesn't make high quality glass.I study influence of different silica raw materials on Na-Ca-Si glass properties in this essay, and discss influence of different soaking time on glassproperties.I analysise diversity of different silica raw materials,and this be propitious to raw material of glass factory and supply advice for glass factory in raw mineral materials.This article from ordinary making-Ca-Si glass is based on the corresponding temperature system, using in mineral resources except siliceous raw material guarantee of other changeless mineral raw materials, at the same time ensure consistent temperature system under the condition of the temperature system.In this essay, I study Na-Ca-Si glass,make I research Na-Ca-Si glass's property, use the mineral materials of glass factory in someway temperature, make use of XRD and analysis structure of the samples, and make some testing.and so on. Decide which kind of glass is the best.The consequence:1.The bubble of glass which made of Qichun and Changli silica raw materials are less.because they own higher purity and stable composition.2.The transmisivity of glass is between 80% and 90%, Qichun glass> Dangyang glass> Shahe glass> Changli glass>Yuanan glass>Anhui glass>Shimen glass.3. The contact angle of glass:Yuanan glass> Shimen glass> Qichun glass> Changli glass.4.The breaking strength of glass:Qichun glass> Changli glass> Shahe glass>Yuanan glass>Dangyang glass>Shimen glass>Anhui glass5.The microhardness of glass:Qichun glass> Changli glass>Yuanan glass>Anhui glass>Dangyang glass>Shimen glass. 6.The expansion coefficient of glass:Shimen glass.>Dangyang glass>Yuanan glass> Changli glass>Anhui glass> Qichun glass7.If Prolonging soaking time, glass's bubble will be less, the melted properties will be better.8.In one word,the properties of Qichun glass are best in synthetical angle.
