Abstract

The invention discloses an anti-static ceramic material and a manufacturing method thereof. A partially stabilized zirconia ceramic material is used as a base body of the anti-static ceramic material, a surface modification layer with the thickness being larger than or equal to 2 micrometers is arranged on the surface of the base body, and the surface modification layer contains iron elements and carbon elements. The manufacturing method of the anti-static ceramic material comprises the steps that the partially stabilized zirconia ceramic material is placed in a high-temperature crucible and embedded by iron powder, then graphite powder covers the iron powder which is in direct contact with air, the high-temperature crucible containing the partially stabilized zirconia ceramic material, an iron powder embedded layer and an graphite powder layer is placed in a resistance furnace to be heated to the temperature of 1000 DEG C to 1400 DEG C, thermal insulation is conducted for 2-20h, after cooling, the graphite and the iron attached to the surface of the high-temperature crucible and the surface of the ceramic material are removed, and the anti-static ceramic material is obtained. The anti-static ceramic material has the good anti-static function, the technology of the manufacturing method is simple, operating is convenient, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of preparation of special ceramic materials, and in particular relates to an antistatic ceramic material and a preparation method thereof. Background technique [0002] Static electricity is very common in industrial fields such as electronic information, petrochemical, textile, paint, grinding and crushing, and fireworks. The accumulation of electrostatic charges is likely to cause great harm. For example, the accumulation and discharge of electrostatic charges can easily interfere with the operation of precision instruments and even burn down microelectronic components. The annual loss of electronic components due to static electricity in the United States is about 10 to 20 billion US dollars. Static electricity accumulation will lead to dust and bacteria in medicine or ultra-clean space; it is easy to cause fire and explosion in mines, petrochemical enterprises and fireworks enterprises; in powder industr...
