Feldspar

Feldspar

Feldspar & Pegmatite can play vital roles during firing as they are used as the main vitrifying or fluxing agent in ceramic bodies & glaze. Alfa Group, as the leader in industrial minerals, has unmatched knowledge of minerals and its characteristics and thus can assist customers in ensuring that the proporations of feldspar in the body recipe are exactly right to avoid over vitrification during firing.

Properties : Feldspar & Pagmatitie strengthen and ensure the durability of fired bodies. Alfa agroup offer feldspar high content with low iron and titanium, which are essential for whiteness and translucency. Through a stringent control of the production processes, our feldspar provide the tableware manufacturer with the assurance that fusibility of the product would satisfy technical requirements. Pagmatites are rocks composed of several minerals : usually Potassium feldspar, Quartz and a little Kaolin, which are suitable for white tableware because of low colouring oxides and also provide a natiral fluxing capability.
