Refractory solutions for Galvanizing and Zinc Oxide

Our refractories offer increased thermal performance, longer component life and higher production output. With a wide range of materials and manufacturing capabilities, Saint-Gobain is a trusted supplier to many zinc production facilities.

High oxidation resistance Cryston® materials offer superior resistance to oxidation and chemical attack.

Muffle furnaces

Saint-Gobain Performance Ceramics & Refractories has introduced a third generation of silicon carbide (SiC) refractories designed to effectively protect copper furnaces. Dedicated R&D teams have developed high performance materials that offer an industry-leading service life. In the field, experienced engineers apply their design expertise to deliver refractory systems that enhance furnace performance, reliability and service life.

Zinc Oxide (ZnO) production requires an exceptional refractory material to form the radiant roof of the muffle furnace. Our Cryston® Max oxy-nitride bonded SiC stands above the rest, offering excellent heating performance over a long, reliable service life. The oxidation resistance of Cryston® Max means that it outlasts competitive materials, while maintaining consistent thermal output throughout its whole lifetime.


As a result, our customers enjoy higher production levels with less fuel consumption.
