2019-10-9 · Orthoclase, or orthoclase feldspar (endmember formula K Al Si 3 O 8), is an important tectosilicate mineral which forms igneous rock.The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar.The gem known as moonstone (see below) is largely composed of orthoclase.
Feldspar contains alumina, which results in an increase in the strength of the manufactured product. Therefore, this mineral is used in glass-making. It is used as a filler agent for plastic, rubber, and paint. It is used to make porcelain, sanitary ware, and tableware. It is used in making mild abrasives, latex foam, and urethane.
This mineral is often called potassium feldspar or K-feldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 C, respectively.
