feldspar
Feldspar is the most important rock-forming mineral for surface rocks. Feldspar is a general term for feldspar minerals, which are a common class of aluminosilicate rock-forming minerals containing calcium, sodium and potassium.

Feldspar is an aluminosilicate mineral containing calcium, sodium, and potassium. It has many kinds, such as albite, anorthite, barium feldspar, baro feldspar, microplagioclase, orthoclase, feldspar and so on. They all have a vitreous sheen and come in a variety of colors. There are colorless, white, yellow, pink, green, gray, black, etc. Some are transparent, some are translucent. Feldspar itself should be colorless and transparent. The reason why it is colored or not completely transparent is because it contains other impurities. Some form blocks, some form plates, some form columns or needles, etc.

Application


Feldspar rich in potassium or sodium is mainly used in ceramic industry, glass industry and enamel industry. Feldspar, which contains rare elements such as rubidium and cesium, can be used as a mineral raw material for extracting these elements. The beautifully colored feldspar can be used as a decorative stone and as a secondary gemstone.

The proportion of feldspar in the crust is as high as 60%, and it can occur in igneous rocks, metamorphic rocks, and sedimentary rocks. Feldspar is the main mineral component of almost all igneous rocks and is of great significance for the classification of rocks
