[0057] According to another aspect of the present invention, the embodiment of the present invention also provides a method for preparing the above-mentioned composite ceramics, comprising the following steps: mixing MgO, SiO 2 , MnO 2 、Al 2 o 3 、Cr 2 o 3 , ZrO 2 , SiC, TiO 2 , monomer carbon, negative ionpowder, germanium stone, volcanic stone and kaolin are added to the ball mill according to the formula ratio, and an optional cationic dispersant is added, the ball mill is uniform, and iron is removed by sieving, and the slurry is made after heating and activation. molding, dewaxing, sintering, and polishing to obtain composite ceramics; preferably, the molding method is hot die-casting.
[0058] The above preparation method prepares the composite ceramics by ball milling and mixing the raw material components and then hot die-casting, which not only can effectively ensure the dimensional accuracy of the composite ceramic products, but also can leave uniform pores in ...
Embodiment 1
[0079] According to weight percentage, take the following preparation raw materials: MgO 10%, SiO 2 10%, MnO 2 10%, Al 2 o 3 10%, Cr 2 o 3 10%, ZrO 2 10%, SiC 15%, TiO 2 4%, monomer carbon 1%, negative ion powder 4%, germanium stone 3%, volcanic stone 3%, kaolin 10%.
[0080] The preparation method of composite ceramics is: MgO, SiO 2 , MnO 2 、Al 2 o 3 、Cr 2 o 3 , ZrO 2 , SiC, TiO 2 , monomer carbon, negative ion powder, germanium stone, volcanic stone and kaolin are added to the ball mill according to the formula ratio, and an optional cationic dispersant is added, and the dry ball mill is carried out for 48 hours. After heating and activating at ℃ for 4 hours, add beeswax and a special dispersant for ceramics to make a slurry, carry out hot die casting, wax removal, sinter at 1000 ℃ for 5 hours, and polish to obtain composite ceramics.
Embodiment 2
[0082] According to weight percentage, take the following preparation raw materials: MgO 6%, SiO 2 5%, MnO 2 9%, Al 2 o 3 5%, Cr 2 o 3 8%, ZrO 2 6%, SiC 40%, TiO 2 1%, monomer carbon 1.5%, negative ion powder 1%, germanium stone 5%, volcanic stone 4%, kaolin 8.5%.
[0083] The preparation method of composite ceramics is the same as that in Example 1.

Abstract
The invention discloses a complex ceramic and a preparation method and application thereof and relates to the technical field of ceramic materials in order to solve the technical problem that the existing ceramic material is relatively weak in antibacterial ability and relatively poor in health-caser effect. The complex ceramic is mainly prepared from the following raw materials in percentage by weight: 1 to 10 percent of MgO, 2 to 10 percent of SiO2, 5 to 10 percent of MnO2, 1 to 10 percent of Al2O3, 5 to 10 percent of Cr2O3, 5 to 10 percent of ZrO2, 10 to 40 percent of SiC, 1 to 5 percent of TiO2, 0.5 to 2 percent of free carbon, 1 to 5 percent of negative ionpowder, 1 to 5 percent of germanite, 2 to 5 percent of pelelith and 5 to 10 percent of kaolin. The complex ceramic provided by the invention is applied to household appliances, so that the household appliances have the functions of household appliances as well as a health-care effect and can radiate far infrared rays and negative ions, and after corresponding household appliances are used for a long time, human metabolism is enhanced, fatigue is eliminated, ageing is resisted, and functions of a human body are improved.
Description
technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a composite ceramic and its preparation method and application. Background technique [0002] With the development of society and the improvement of living standards, people are paying more and more attention to environmental protection and health, especially in terms of daily necessities, for example, the health performance requirements of ceramic materials contained in household appliances are getting higher and higher. [0003] Negative ion material is a compound mineral that is artificially synthesized or proportioned. Because it has pyroelectricity and piezoelectricity, it can cause a potential difference between the component crystals under the condition of temperature and pressure changes (even small changes) , this static electricity can be as high as 1 million electron volts, so that the air is ionized, and the electrons that are hit attach to adjacent water an...
