Potassium Feldspar is one of the most abundant and important group of minerals in the earth’s crust. It is a type of Feldspar rich in potassium Oxide (K2O), primarily sourced from potassium rich minerals like orthoclase and microline. This powder is widely used in the ceramics industry, particularly for making glass and porcelain. It helps lower the melting temperature of ceramic materials. Boosts durability, and enhances the quality of the finished products. Additionally, potash feldspar powder is commonly used in the production of glazes, enamels, and other materials that demand high potassium levels.
We are offering potassium feldspar lumps, soda feldspar powder. Potash and soda feldspar occur as essential constituents of granite, syenite and gneisses. However, workable deposits are found in pegmatite veins consisting mainly of feldspar, quartz-feldspar veins and also occur with mica pegmatites. Feldspar is of widespread occurrence and is mined in almost all countries. Feldspars are aluminosilicates. Their fusibility and purity make them a useful raw material with many industrial applications.
we supply feldspar mainly in forms of lumps, grainschips and powder.
