High-infrared-emitting-ability cordierite-spinel ceramic material and preparation method thereof
The invention discloses a high-infrared-emitting-ability cordierite-spinel ceramic material, and belongs to the technical field of preparation of ceramic materials. The high-infrared-emitting-ability cordierite-spinel ceramic material comprises the following raw materials in percentage by mass: 25-80% of pulverous coal, 10-25% of magnesia and 10-55% of alumina. The invention also discloses a preparation method of the material. Costs of the raw materials are greatly reduced, performance of products is excellent, and principal crystalline phases comprise a cordierite phase and a spinel phase. The high-infrared-emitting-ability cordierite-spinel ceramic material has the advantages of high radiance, small thermal expansion coefficient, good thermal shock resistance and the like, and is multifunctional. Sintering temperature is greatly reduced; when the minimum temperature is 1230 DEG C, the infrared ceramic material can be fired, temperature is easy to control, and infrared emitting ability of fired ceramics is quite high, and can be similar to that of a pure cordierite ceramic material. By the preparation method of the high-infrared-emitting-ability cordierite-spinel ceramic material, wastes can be reused and can be changed into things of value, and economic benefit and social benefit are excellent.
