Glass and Glass making
products |
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. |

Na2O+K2O10% |
|
Ceramic industry |
Feldspar as blank material in the production of ceramic,
enamel, electrotechnical porcelain products (20-40% addition)
and as raw materialto glaze (20-70% addition) |
Fe2O30.3-1.0% |
|
Cement industry |
As one of raw material to producing white cement |
|
|
Chemical Processing |
Crushed feldspar can be used as filling material to latex,
painting,carbamic
acid, acetic acid, propylene or like 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. |
