intermediate sodium-rich feldspars (albite) to potassium-rich, felsic, feldspars (orthoclase). These minerals have been documented, studied and analyzed both qualitatively and quantitatively throughout the history of geology. Due to this long history of study, most of the physical properties and paragenesis of feldspars are well understood.

Feldspars of importance to ceramics are aluminosilicates of sodium, potassium, and calcium (Jones & Berard, 1993) They are used as fluxes to form a glassy phase in bodies, thus promoting vitrification and translucency.They also serve as a source of alkalis and alumina in glazes. The pure spars are albite (NaAlSi 3 O 8), orthoclase or microcline …

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

Origin and occurrence. Feldspars occur in all classes of rocks. They are widely distributed in igneous rocks, which indicates that they have formed by crystallization from magma.Physical weathering of feldspar-bearing rocks may result in sediments and sedimentary rocks that contain feldspars; however, this is a rare occurrence because in …

Alkali feldspars comprise K-feldspar (K[AlSi 3 O 8]) and Na-feldspar or albite (Na[AlSi 3 O 8]).K-feldspars are characterized by a monocline structure at high-temperature, with Al randomly substituting Si in all tetrahedral sites (called T 1 o, T 2 o, T 2 m, and T 1 m). The resulting structure is monoclinic and known as sanidine.The tetrahedral sites have not …

Feldspar is the most abundant mineral group in the Earth's crust. There are more feldspars (60%) than all the other minerals combined in the outer (13-17) km of the crust 1. Feldspars occur in most igneous and metamorphic rocks. They are less common in sedimentary rocks as they tend to break down to clay minerals in the weathering environment.

Feldspars are utilised as functional fillers in the paint, plastic, rubber, and adhesive industries, as well as as fluxing agents in ceramics and glass applications. The alkali and alumina content of feldspars are the two qualities that make them valuable for downstream industries. Three groups of elements can be distinguished based on those
