Key properties

Feldspar & pegmatite strengthen and ensure the durability of fired bodies.

Imerys Ceramics offers high potassium content with low iron and titanium, which are essential for whiteness and translucency. Through a stringent control of the production processes, Imerys Ceramics’ feldspars provide the tableware manufacturers with the assurance that the fusibility of the product satisfies technical requirements. 

Pegmatites are rocks composed of several minerals: usually potassium feldspar, quartz and kaolin, which give a natural fluxing capability and, because of low coloring oxides, are especially suitable for white tableware.

Our worldwide technical support team is at your service and is dedicated to help you reach your Challenges.
