Saint-Gobain Ceramic Materials, Boron Nitride Products, recently announced the launch of its Combat® boron nitride-grade SiZBN, particularly geared for molten metal applications where high-temperature strength and wear resistance are key. SiZBN, a hot-pressed composite ceramic, reportedly combines the lubricating properties of boron nitride, extreme refractoriness of zirconia, and wear resistance and strength of SiAlON. According to Saint-Gobain, its newest composite is ideal for components requiring strength at high temperatures in a variety of molten metals and steel contact applications. SiZBN parts are reportedly easily machined into complex, intricate shapes, with very smooth finishes and tight tolerances.

“SiZBN is an extension to our boron nitride composite family that includes boron nitride, zirconia, silicon carbide and silica composites—grades ZSBN, M and M26,” said Neelam Kumar, product manager for Combat components. “Our grade ZSBN—a boron nitride, zirconia and silicon carbide composite—is a market-leading grade for steel and molten metal manufacturing. The addition of SiZBN to this family of composites allows us to help our customers tackle new challenges in steel casting, specialty alloy manufacturing and a variety of powder metal applications. The new SiAlON composite further strengthens our position into spaces where improved strength and wear resistance at temperatures above 1,400°C are required to extend production cycle and improve product quality.”
