รับราคาFeldspar Feldspar 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 feldsparrich rocks larvikite and a few anorthosites are employed as both interior and exterior facing slabs.

Diffusion of argon in feldspar is important because of its significance to KAr geochronology and becomes especially so with increasingly widespread use of both plagioclase and alkali feldspar for dating by the 40 Ar/ 39 Ar technique. Despite study and debate for more than 30 years, the basic feldspar Ar transport phenomena are subject to considerable uncertainty.

High concentrations of alumina (Al 2 O 3) and alkalis (K 2 O and Na 2 O) together with low levels of trace elements such as iron (reported as the oxide Fe 2 O 3) define a highquality feldspar product.Alumina adds hardness, durability and resistance to chemical corrosion while the alkalis act as a flux lowering
