Dolomite and limestone are the third major components of glass materials except silica sand and soda powder. In the production of bottle glass, soda powder is an expensive component. Adding limestone can partially replace soda powder, but it will have adverse effects. The introduction of magnesium oxide in dolomite can further reduce the cost. Dolomite in the glass industry can also provide calcium oxide, add soda ash silica system, play the role of flux.
In addition, dolomite powder (snowflake white) 1250 mesh can also reduce glass aging, prevent chemical erosion caused by atmosphere or water, improve the plasticity of colored glass and increase glass strength. Adding a certain amount of dolomite powder to glass can effectively reduce the high temperature viscosity of glass and improve the chemical stability and mechanical strength of products. The practice also shows that the energy consumption can be significantly reduced by introducing dolomite powder in the preparation of low temperature ceramics and float glass.
