Feldspar is a mineral that accounts for up to 60% of the Earth's crust. Feldspar is divided into two types, both of which are composed of silica and aluminium. In 2010, about 20 million tons of feldspar were produced, mainly by three countries: Italy (4.7 million tons), Turkey (4.5 million tons), and China (4.5 million tons) (2 Mt).

Feldspar incorporated into the mix carries out two important functions namely (i) It acts as an arc stabiliser, & (ii) helps in weld pool protection. In the case of weld pool protection, slag formers such as felspar form a molten/solid barrier to protect the weld pool and new weld metal. Feldspar can form between 5 and 10% of the total dey ...

Feldspar - Mineralogy, Identification, Uses: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some …

Feldspar minerals are some of the most abundant minerals within the Earth's crust and are a common component of rocks. Species that are rich in potassium (K) are called potassium feldspars. Orthoclase, Microcline (Amazonite), and Sanidine are potassium feldspars. Feldspars rich in sodium (Na) or calcium (Ca) are plagioclase feldspars.

In fact, feldspar is the standard for hardness 6 in the Mohs scale. Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff. They usually have a glassy luster. Feldspar is called a rock-forming mineral, very common, and usually makes up a large part of the rock.
