Feldspar

Feldspar

Persol Feldspar is produced from prepared natural raw minerals. All data are approximate values with tolerances depending on occurrences and production. They only serve as description and do not represent any warranty concerning the existence of specific characteristics. Traces of coarser particles may be possible. It applies to the user to test the suitability for his purposes. If wanted, we are prepared to give further information on tolerances and on our experience in technical applications. Sales are subject to our sales and delivery conditions.

Our grades feature an extremely high quality consistency, extremely low iron and titanium contents and a very high total feldspar content. The versatility of uses ranges from glazes and frits to bodies for the tableware, sanitary ware and insulator and tile industries as well as in the glass industries.

Potassium feldspar is widely used in industrial departments such as ceramic blank, ceramic glaze, glass, porcelain, Fillers, Paint, grinding materials (Mild Abrasives) and potash fertilizer production.

Potassium feldspar refers to a number of minerals in the feldspar group and contains potassium in a monoclinic crystal system. Usually, they’re flesh red, white or gray. The density of feldspar is 2.54-2.57 g/cm3, specific gravity is 2.56-2.59g/cm3, hardness is 6 and it has main characteristics such as low melting point (1150+ 20℃), long melting interval and high melting viscosity.
