Welcome to Imerys Performance Minerals


FELDSPAR Natural fluxing agents for whiteness and superior translucency for a range of ceramic applications.

Feldspars play vital roles during firing as they are used as the main vitrifying or fluxing agent in ceramic bodies. Using feldspar in ceramics production strengthens and ensures the durability of fired bodies.

Imerys feldspars are characterized by their high alkali content and low iron and titanium content, which are essential for whiteness and translucency in tableware and sanitaryware

Through a stringent control of the production processes, Imerys is able to design feldspars that provide tableware manufacturers with the assurance that the fusibility of the product satisfies technical requirements.
