High temperature resistant materials usually refer to inorganic materials that can withstand temperatures above 1580°C. They are used in the construction of kilns, combustion chambers and other construction materials that need to withstand high temperatures. It is generally made of quartz sand, clay, magnesite, dolomite, etc. as raw materials, such as refractory cement, magnesia bricks, etc. There are also non-intermetallic compounds such as boron carbide, silicon carbide, boron nitride, silicon nitride, boron phosphide and silicon phosphide, which are often used in aerospace materials, nuclear engineering materials and jet engine combustion chamber materials F1 engines; the resistance of these materials The high temperature is much higher than the 1300℃ you mentioned. The simplest example is that the engine temperature of a jet engine has exceeded 1500℃ when it reaches its limit. Not to mention the high temperature resistance of aerospace and nuclear engineering materials
