POTASH Feldspar Powder for Glass industry
Potash Feldspar Potassium Feldspar for glass industry
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.
Manufacturer and supplier for Potassium Feldspar - Potash Feldspar Powder
In glass manufacture, feldspar is used as fluxing agent and as a source of alumina (Al2O3), alkali (Na2O and K2O), and silica [3]. Fluxing agents are substances, usually oxides, used in glasses, glazes and ceramic bodies to lower the high melting point of the main glass forming constituents, usually silica and alumina.
POTASH Minerals are frequently used in glass manufacture and in ceramics. In glass applications feldspar is used for container and flat glass, fibreglass, TV-tube glass, and other more specialised uses. The chemical composition of the feldspar product is important for the applications in glass manufacture.
Feldspar is commonly used to produce glass with excellent optical properties and strength for industrial and chemical applications.
