Potash Feldspar and Powder

Feldspar (predominantly orthoclase phase) is one of the forms of feldspar.

It is a silicate of aluminum containing potash, soda etc which forms with even cleavage planes. Potash feldspar is distinguished from the other forms by its content of potassium.

Endura offering fine quality high purity feldspar both lumps and powder form. Our product has always stand distinct with its uniqueness in comparison with other competing products.

FAQ

What is potash powder used for in ceramics?
Potash powder acts as a flux in ceramic production. It lowers the melting temperature of other raw materials, helping tiles and sanitaryware vitrify properly and achieve a dense, glossy surface.
Bright white feldspar with low Fe₂O₃ (<0.2%), high K₂O (>10%), and fine mesh size (≥200) ensures maximum gloss and clarity in glossy wall/floor tiles.
It vitrifies effectively around 1,200 °C, promoting dense and durable tile bodies while imparting a clean white colour.
Primarily the vitrified tile industry, but also used in ceramics, sanitaryware, glassmaking, and abrasives due to its fluxing and strengthening properties.
Potash feldspar is a naturally occurring mineral rich in potassium. Potash powder typically refers to finely ground feldspar or potassium-rich compounds processed for industrial use.
Not always. Potash feldspar offers better performance in high-end products, but soda feldspar is preferred where cost is a bigger concern. Many formulations use a mix of both.
