The composition and use of feldspar

The most common minerals in the earth's crust are feldspar, which are often found on the moon and in meteorites. In the depth of 15 kilometers underground, feldspar accounted for 60% of the total weight in the crust. Feldspar is the main component of igneous rocks, and is also common in metamorphic and sedimentary rocks. Feldspar generally in volcanic rocks and metamorphic rocks, feldspar are very small, only 0.1 to 10 mm. In porphyry, feldspar length of up to 5 to 10 cm, and in some pegmatites up to tens of meters. Feldspar is the raw material for ceramics and glass industry. Some feldspar has a beautiful color or dizzy color, can be used as a gem material.

Feldspar is an aluminosilicate mineral of alkali metals and alkaline earth metals such as potassium, sodium, calcium and barium. Its main chemical components are SiO2, Al2O3, K2O, Fe2O3, Na2O and CaO, which are important rock-forming minerals. Feldspar is mainly used in the manufacture of ceramics, enamels, glass raw materials, abrasive and other abrasive, in addition to the manufacture of potash fertilizer.
