Discover the Versatility of Feldspar
Feldspar and pegmatite play vital roles during the firing process, serving as the main vitrifying or fluxing agents in ceramic bodies and glazes. As a leader in industrial minerals, Alfa Microns possesses unmatched knowledge of mineral characteristics and can assist customers in ensuring that the proportions of feldspar in body recipes are precisely balanced to prevent over-vitrification during firing.
Feldspar is the most abundant group of minerals in the Earth’s crust, and its use in industrial applications is widespread. In fact, feldspar can be found in many of the everyday products we use.
Properties: Feldspar and pegmatite enhance strength and ensure the durability of fired ceramic bodies. Alfa Microns offers feldspar with high content and low levels of iron and titanium—essential qualities for achieving whiteness and translucency. Through stringent control of production processes, our feldspar provides tableware manufacturers with the confidence that the product’s fusibility will meet all technical specifications.
Pegmatites are rocks composed of several minerals, typically including potassium feldspar, quartz, and small amounts of kaolin. They are especially suitable for white tableware due to their low content of coloring oxides and their natural fluxing capability.
