Abstract

The invention relates to a far infrared ceramic material. The material is multi-element mixed superfine powder which is prepared by mixing the following components in part by weight: 5 to 15 parts of zirconium oxide, 10 to 30 parts of zirconium silicate, 5 to 15 parts of feldspar, 10 to 20 parts of alpha-alumina, 5 to 15 parts of manganese oxide and 1 to 3 parts of boron nitride, wherein the average particle size of the multi-element mixed superfine powder is less than or equal to 1 micron. The zirconium oxide, the alpha-alumina and the manganese oxide in the raw materials adopted by the far infrared ceramic material have high far infrared emission performance; a coating which is formed by the zirconium silicate and the feldspar has compactness and high-temperature resistance; and the boron nitride has lubricity and adhesion resistance. The far infrared ceramic material is suitable to be applied to boiler water wall tubes, heating tube walls, high-temperature drying rooms and the like.
