Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to a high-voltage-resistant insulating positioning ceramic material. Background technique [0002] The positioning part is a part that participates in restricting the free movement of the article. In a mold composed of two or more parts, it is a positioning part designed to accurately position the adjacent two parts of the mold. As a very important mechanical basic component of contemporary mechanical equipment, positioning parts are widely used in various fields of science and technology and economy. Existing positioning parts can be divided into positioning metals, positioning plastics and positioning ceramics. Positioning metals have poor corrosion resistance, non-wear resistance and conductivity, and are not suitable for some special fields; positioning plastics have poor hardness, are easy to deform, are not resistant to high temperatures, and have a shor...
