Aug 10, 2019· The high potassium content and high strength of K-feldspar make it the best mineral for potassium-argon dating. Alkali feldspar is a crucial ingredient in glass and pottery glazes. Microcline has a minor use as an abrasive mineral.
Petrologists distinguish the position of a plagioclase along this series using two numbers- %Ab (percent albite) and %An (percent anorthite.) Plagioclases are triclinic and have a Moh's hardness of 6 to 6 ½. The pure sodium feldspar, albite has the formula NaAlSi3O8 and the pure calcium endmember, anorthite has the formula CaAl2Si2O2.
Potassium feldspars are a significant component of many felsic igneous rocks used as decorative building stones. By volume, however, the most significant use of potassium feldspar is as aggregate in concrete and asphalt. Large volumes are also used in the .
Feldspar is a common raw material used in glassmaking, ceramics, and to some extent as a filler and extender in paint, plastics, and rubber. In glassmaking, alumina from feldspar improves product hardness, durability, and resistance to chemical corrosion.
Oct 16, 2019· Feldspar is a very versatile material, and is used in a wide variety of products worldwide. Here in the United States where I live, over half of all feldspar in use goes to making glasswares, like dishes and windows and such.

The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana's System of Mineralogy lists the intermediary members as individual minerals, whereas ...
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.
