Abstract

The invention discloses an anti-static zirconia ceramic. The anti-static zirconia ceramic is prepared from the following raw materials in parts by mole: yttria-stabilized zirconia, sodium oxide, aluminum oxide, calcium oxide, nickel oxide, chromium sesquioxide, manganous-manganic oxide and conductive carbon black. The preparation process of the anti-static zirconia ceramic comprises the following steps: 1) sufficiently carrying out ball milling on the yttria-stabilized zirconia; 2) mixing the ball-milled yttria-stabilized zirconia, sodium oxide, aluminum oxide, calcium oxide, nickel oxide, chromium sesquioxide, manganous-manganic oxide and conductive carbon black and then sufficiently sanding and mixing; 3) adding a binder in above mixture, and pelleting; and 4) placing above spherical particle in a die at room temperature to perform compression forming, hot-pressing to degrease and sintering; after sintering, naturally cooling to room temperature. The zirconia ceramic product produced by the invention is good in chemical stability, high in hardness, high temperature resistant, abrasion resistant, corrosion resistant, strong in insulation, and obvious in anti-static performance advantage, and has good application prospect.

Description

technical field [0001] The invention relates to an antistatic zirconia ceramic and a manufacturing process thereof. Background technique [0002] Zirconia ceramic materials have the characteristics of high hardness, high temperature resistance, wear resistance, corrosion resistance, antimagnetic, insulation and so on. However, due to factors such as ambient temperature, humidity and its own structure, in some special cases, zirconia ceramic materials have the property of allowing electric current to pass through, which may cause electrical conductivity and static electricity. Therefore, the nature of zirconia ceramic materials determines the use environment. Improving the antistatic performance of zirconia ceramic materials, and further comprehensively improving the hardness, wear resistance, corrosion resistance, etc. of zirconia ceramic materials, so that they can be widely used in more harsh environments, has always been a solution for those skilled in the art. technica...
