Feldspar:Feldspars are the most common mineral group found on the earth'scrust ,constituting approximately 60percent of it;nearly 90 percent of magmatic and metamorphic rocks and 15 percentof sedimentary rocks are feldspars.Tcalhis group is dividedinto alkali Na feldspars
Sodium Feldspar using,Ceramic and Glass endustry very much ,Ceramic factory using Glaze,frit and body formulation,in galze and frit using powder (-75 mic ) body formulation inside using less than 1 cm ,good qualiy sodium feldspar must be min.NaO % 9.5 and very less irion and titanium volue (max. 0.5%)
Sodium feldspar rezerve % 70 in Turkey and mine aria Çine-Aydın location
Chemical formula: Na2O3.AL203.2Si02(Albit-Na Feldspar)
Application: Ceramic,Glass,paint,plastics,cement,rubber ext.
