The main vitrifying agent In ceramic body is feldspar. The majority of white ware bodies contain good proportions of feldspar. It acts as a flux. In the ceramic industry, the flux is defined as that portion of the body which develops glass phase. This is provided mostly by feldspar. The amount of flux in a ceramic body should be only in such a proportion as to develop the desired amount of vitrification. If excess of flux is added, the fired body becomes very glassy and consequently, brittle.
Our mines have best quality of potash feldspar with K2O content of 11% to 12% and almost NIL Iron Content. We also have a fully automatic production unit in the state of Rajasthan and Andhra Pradesh to produce materials as per requirement of our valued customers. We have our in house Laboratory to test the material produced in every batch.
Potash Feldspar is mainly used in Ceramics and Glass Industry.
