Feldspar is a major vitrifying (fluxing) agent that is used in almost all ceramic bodies. Especially white water bodies contain a good proportion of feldspar. This is highly demanded in the ceramic industry, as it acts as a flux and the industry defines it as a portion of body that develops glass phase. The producers of ceramic products, make use of flux in proportion required to develop the desired amount of vitrification. Excess of flux can result in relatively more glassy and brittle body, once fired. Apart from ceramic, it also finds usage in Glass, and Electrodes. It is also used as Catalysts, Decorative stone, binding agent in False Teeth. Around 95% of the total consumption of feldspar is by ceramic and glass industry. Feldspar, the name itself defines presence of Aluminum Silicate of calcium, sodium and potassium.
Potash feldspar is an economical fluxing agent widely used in the production of ceramic items, such as compounding of tiles, tableware items, sanitary wares, insulators, etc. Also called potassium feldspar, it is also used in glass production and abrasive wheels. The aluminum supplied by it in the production improves the strength, and transparency of flat glass, glass wool and hollow glass. It is also used in paints, insulation, rubber and plasters, as a filler. The customers can avail this rock mineral in different structures. Compared to soda feldspar, potash feldspar has more refractory effect on the ceramic surface.
Features of Potash feldspar:
1. Custom-made ranges available.
2. Attractive colors and appearance.
3. Contains high amount of minerals.
4. Application in wall tiles, ceramic floors, glassware, and many more products.
