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

All high-temperature industrial operations necessitate the use of refractories. Every reactor, transport vessel, and kiln is lined with a variety of refractory materials, including bricks, monolithic, and high-temperature insulating wool. Refractories perform three functions: mechanical strength, corrosion resistance, and thermal insulation. They are fine-tuned and a careful selection of raw materials and processing methods are used to tailor them to each specific use. Innova
