Feldspar comprises a group of minerals containing potassium,
sodium, calcium and aluminium silicates. They are the most common
gray, no color
Feldspar used as raw material of glass industry (50-60% total
consumption) and ceramic industry (30% total consumption), besides,
it is widely used in chemical processing, abrasive tools, glass
fiber and welding rod industries.
Glass and Glass making
Feldspar as raw material of flat glass and
kinds of glass make products, it can decrease the glass
melting point, reduce the use of calcined soda.
Sodium feldspar as raw material of glass fiber can
improve the fiber quality and as substitute of pyrophillite.
Feldspar as blank material in the production of ceramic,
enamel, electrotechnical porcelain products (20-40% addition)
and as raw materialto glaze (20-70% addition)
|Cement industry||As one of raw material to producing white cement|
Crushed feldspar can be used as filling material to latex,
painting, carbamic acid, acetic acid, propylene or similar products.
As filler, bigger content of
free quartz is preferred;
as filler to cosmetic powder,
2-8um alkali feldspar is required.
|Abrasives||Powdered feldspar can be used in abrasive industry.|
wide applications are found in paper making, refractory product, machine manufacturing.
