Low Fe2o3 Good Price Dolomite for Glass Industry

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

 

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.
