Abstract

The invention relates to a preparation method of infrared radiation ceramic powder in a spinel-silicate multi-phase composite system. The preparation method comprises the following steps: firstly, various raw materials are taken at a specified ratio, and then the primary processing of milling, mixing, drying and press-molding on the raw materials to form a blocky blank is carried out, and the obtained blocky blank is subjected to heating and heat preservation at the temperature in the range of 800 DEG C to 980 DEG C to form a spinel-type solid solution; then the temperature is continually heated up to 1100 DEG C to 1300 DEG C to heat and preserve heat of the blocky blank to form a silicate mineral, the spinel-type solid solution and the silicate minerals are composited in a multiphase way to form a black sintered body with a multiphase composite structure; and the obtained black sintered body is crushed, ground and sieved, so that the infrared radiation ceramic powder in the spinel-silicate multi-phase composite system can be obtained. The raw materials used in the invention are ordinary raw materials which are extensive in sources, the preparation method is simple and practical, short in production cycle and low in manufacturing cost, can be used in infrared radiation energy-saving coatings, infrared radiant heaters and the like of a high temperature industrial furnace (boiler), and has wide application prospect.
