Potassium Feldspar By Perfect International For Mining

Credited amongst one of the credible market names, we are enthusiastically affianced in exporting, trading, distributing, manufacturing and supplying an excellent quality collection of Potassium Feldspar in Cairo, Egypt. Potassium Feldspar is an important tectosilicatemineral which forms igneous rock. It is a common constituent of most granite and other felsicigneous rocks and often forms huge crystals and masses in pegmatite. 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 (calcium oxide, potassium oxide, and sodium oxide) 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.
