Image Credit : Google In conditions such as glass, fiberglass, or enamel furnaces, the resilience of refractory materials to heat stress and alkali corrosion is of great interest. In such conditions, refractory materials are commonly used to protect burners. Burner blocks, which are dedicated to this purpose, are subject to special limits that necessitate the use of high-performance materials. In contrast to silica and alumina, zirconia has a great resistance to alkali diffus

1. Refractory: refractoriness refers to a material's resistance to melting at high temperatures. The chemical composition of the refractory and the content of fusible impurities (such as FeO, NaO, and others) in the material determine its refractoriness. Because the high temperature load under the softening temperature of the refractory material will be reduced, the actual permissible use of refractory temperature is higher than the refractory, refractory does not represent t

Refractories are defined as “nonmetallic materials with the chemical and physical qualities that make them applicable for structure or as components of systems exposed to conditions exceeding 1000 °F / 538 °C” according to ASTM C71. Superior mechanical properties at room and high temperatures, the capacity to withstand rapid temperature flu
