Soda feldspar is a volatile substance and has excellent moisture absorbent capacity due to which this compound melts when it comes in contact with the atmosphere. Glass Industry. In glass-making, it provides aluminium that enhances the strength and transparency of hollow glass, flat glass, decorative glass and insulating glass.
In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Glass and ceramics continued to be the major end uses of feldspar.
A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass.
