Feldspar

Feldspar offered by our company is a natural and pure chemical compound, which is used extensively in porcelain manufacturing units. Feldspar, which is a naturally occurring anhydrous, inorganic, igneous rock, is a complex of aluminum silicate containing varying amounts of sodium, potassium, and calcium. Feldspar is by far the most abundant group of minerals in the earth’s crust, forming about 60% of terrestrial rocks. Most deposits offer sodium feldspar as well as potassium feldspar and mixed feldspar. The Feldspar we are supplying is widely used in the Ceramic industries, Glass industries, Paints & Coatings (Chemical Resistant Coatings, Anti-skid/Anti-slip Coatings, Pipeline Coatings, etc). Feldspars are primarily used in industrial applications for their alumina and alkali content.
Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. In the manufacture of ceramics, feldspar is the second most important ingredient after clay. They improve the strength, toughness, and durability of the ceramic body, and cement the crystalline phase of other ingredients, softening, melting and wetting other batch constituents.
Feldspars also are used as fillers and extenders in applications such as paints, plastics and rubber. In tableware, feldspar gives a good fusibility for a product without defects. In sanitary ware, the use of feldspar within vitreous ceramic bodies is used to facilitate the optimization process.
