Abstract

The invention discloses a preparation method of high-wear-resistance crucible ceramic materials. The preparation method comprises the steps that silicon carbide, boron carbide, yttrium oxide, zirconium oxide, nickel silicide, aluminum oxide and silicon dioxide are placed into a ball milling machine to be smashed; the smashed materials and a dispersing agent are placed into a drying box to be dried; the dried materials are fed into a high mixing machine to be mixed, and a mixture a is obtained; the mixture a is fed into a forming machine, meanwhile, a binding agent is added, press forming is carried out, and a mold blank is obtained; the formed mold blank is presintered, and a presintered blank is obtained; and the presintered blank is sintered for 3-5h at the temperature of 1650-1850 DEG C, and the ceramic materials for a crucible are obtained. The crucible ceramic materials prepared through the preparation method has the quite high wear resistance and long in service life, the preparation method is simple, and the forming rate is good.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a preparation method of a high wear-resistant crucible ceramic material. Background technique [0002] In industrial furnaces, crucibles are an important part. Since industrial furnaces are generally used for melting metals, higher requirements are placed on the quality of crucibles. [0003] During the use of the crucible, it needs to be in contact with metals, such as metal aluminum, iron and copper. Since metals are generally relatively hard materials, in the initial stage of melting, in order to conduct heat smoothly, the molten metal should also be stirred. Therefore, the metal object and the crucible will have contact friction. [0004] In the existing crucible, due to its poor wear resistance, its service life is very short, which also greatly increases the cost of metal melting. Contents of the invention [0005] In view of this, the invention provides a pr...
