2019-9-1 · Examples include silicon carbide fibers in a silicon carbide matrix (SiC/SiC) with boron nitride at the interface between them—a material used in cutting-edge gas-turbine jet engines. Photo: Advanced ceramics: Silicon and carbon fuse to form silicon carbide powder (left), which can be made into a hard and hard-wearing ceramic called silicon
2013-3-16 · Glazes, but they are miniscule from the 800 mesh silicon carbide. Many of our glaze chemicals vaporise at cone 9 and they would have more effect on the elements than the silicon carbide. Truthfully, even if it destroyed the elements sooner, getting incredible copper red oxblood glazes in an electric kiln, to me, is worth whatever it costs.
Frits for ceramics and enamels. The boric oxide content of a frit depends on the type of glaze for which the frit is intended: For glazes that are used in ceramic-tile manufacturing, the higher the firing temperature the lower the frit’s B 2 O 3 content; High temperatures or long firing cycles mean a high-heat work, which reduces the amount of boric oxide allowable in the glaze
2002-1-1 · Objective: A comparative investigation of acrylic denture base surface microhardness, induced through glazing with different photo-activated liquids.. Materials and methods: Thermopolymerized acrylic resin Paladon 65 (Kulzer) was used for this study.The samples were mechanically thinned by silicon carbide grinding papers and finally, mechanically polished by alumina pastes.

Glaze does not stick to nitride bonded silicon carbide, so if you own kiln shelves made of this material, it is typically unnecessary to apply kiln wash. However, if you are firing finicky materials - namely porcelain - which can become glaze-like under certain firing circumstances, you might want to use kiln wash to prevent your clay bodies
