The insulating positioning ceramic kit material disclosed by the invention is non-conductive and non-magnetic, has high strength, high toughness and high wear resistance, is not easy to deform, wear and break when working under a high-temperature condition, prolongs the service life of a positioning ceramic kit, and is simple in preparation process and relatively low in processing cost.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to an insulating positioning ceramic kit material and a preparation process thereof. Background technique [0002] The positioning kit is the part that participates in restricting the free movement of the article. In the mold composed of two or more parts, the positioning part is designed to accurately position the two adjacent parts of the mold. As a very important mechanical basic component of contemporary mechanical equipment, positioning kits are widely used in various fields of technology and economy. Existing positioning kits can be divided into positioning metal kits, positioning plastic kits and positioning ceramic kits. The positioning metal set has poor corrosion resistance, wear resistance and electrical conductivity, which is not suitable for some special fields; while the positioning plastic set has poor hardness, easy deformation, high temperatur...
