Feldspar - Feldspar - Uses Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics. The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.
The alkali component in feldspar acts as a fluxing agent, which, in turn, lowers the temperature of the glass, thus making it a great melting agent. Ceramics In the ceramic industry, feldspar and clay are the most widely used raw materials.
Feldspar is commonly used to produce glass with excellent optical properties and strength for industrial and chemical applications. Glass-making requires material that are free from contaminants, consistent in size, and low in iron content. It gives the finished glass products firmness, flexibility, cohesion, and chemical resistance.
In the production of glass feldspar is a critical material. It is also crucial as acting as a fluxing catalyst. Acting as a fluxing catalyst also it to reduce the tempreature of quartz while at the same time keeping the viscosity of the produced glass at the right correct range.What makes feldspar function effectively as a flux in glass making ...
