Dolomite and limestone are the third major components of glass raw materials besides silica sand and soda powder. In the production of bottle glass, soda powder is the most expensive component, adding limestone can partially replace soda powder, but it will have adverse effects, and the introduction of magnesia in dolomite can further reduce costs. Dolomite in the glass industry can also provide calcium oxide, adding soda ash - gray - silica system, play the role of flux. In addition, dolomite can also reduce glass aging, prevent chemical erosion caused by atmosphere or water, improve the plasticity of colored glass, and improve the strength of glass. Adding a certain amount of dolomite powder can effectively reduce the high-temperature viscosity of glass and improve the chemical stability and mechanical strength of the product. The practice also shows that the energy consumption can be significantly saved by using dolomite powder in the preparation of low-temperature ceramics and float glass ingredients.
