Abstract

The invention discloses a new energy automobile ternary system high-performance fuse porcelain tube, which is prepared from the following components: 1.5-4.0% of strontium carbonate, 1.8-4.1% of calcined talc, 92.5-94.5% of aluminum oxide, 1.0-1.5% of kaolin, 0.2-0.5% of quartz, and 1.0-1.3% of cordierite. By adding strontium carbonate, the fuse porcelain tube has high wear resistance and toughness, and is conducive to reducing microstructure after grinding processing, i.e. the occurrence rate of circular pit phenomenon outside a product.

Description

technical field [0001] The invention relates to the technical field of electronic ceramic production, in particular to a ceramic tube for a ternary system high-performance fuse of a new energy vehicle. Background technique [0002] Some high-end customers and markets have high requirements on the surface roughness of fuse porcelain tubes, because the outer surface of the porcelain tube needs to print high-definition key parameters. However, the surface roughness of existing ceramics cannot meet the requirements for high printing. Moreover, ceramics are brittle and hard non-metallic materials. Its grinding mechanism is quite different from that of metal processing. The principle of ceramic processing is: under the action of external force, the abrasive will cause tiny cracks on the surface of the product, and gradually expand and Breaking and breaking away from the product material, that is, the processing state and processing amount of the entire processing surface are accu...
