Division of Geology and Mineral Resources - Feldspar

Feldspar is one of the most abundant minerals in the earth's crust. The feldspars include a range of compositions with a general chemical formula of xAl(Al,Si) 3 O 8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K). They are primarily used in glass and ceramics making.

Feldspar - Chemical composition | Britannica

Perthite consists of intimate intermixtures of a potassium feldspar—either microcline or orthoclase—and a sodium-rich plagioclase that occurs as microscopic to macroscopic masses within the potassium feldspar host.

Feldspar - Wikipedia

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.

Plagioclase Feldspar: A group of common rock-forming …

“Plagioclase” is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8). Minerals in this series are a homogenous mixture of albite and anorthite.

Feldspar Distinctions, Characteristics & Identification

Alkali feldspar has the formula KAlSi 3 O 8, potassium aluminosilicate.The formula actually is a blend ranging from all sodium (albite) to all potassium (microcline), but albite is also one endpoint in the plagioclase series so we classify it there.

Feldspar - Uses | Britannica

Uses. Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics.The feldspar-rich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.
