Feldspar, Silica : SiO2 67.00 %

We are offering feldspar.
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion. In ceramics, the alkalis in feldspar act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together. Feldspar is consumed in glassmaking( including glass containers and glass fiber) , pottery (including tile, electrical insulators, sanitary ware, and tableware) and other uses such as fillers.
