Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a composite high-temperature refractory material and a preparation method thereof. Background technique [0002] A class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1580°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are used in the largest amount in the metallurgical industry, acco...
