Problems solved by technology

However, the performance of ceramic materials composed of a single zirconia is relatively single, which cannot be used in many fields. In order to effectively improve its performance, it is necessary to optimize its ceramic composition and improve the comprehensive performance of zirconia ceramic materials. It is also a hot spot in the field of ceramics

Abstract

The invention discloses a high-performance ceramic material. The high-performance ceramic material comprises the following raw materials in parts by weight: 25 to 38 parts of zirconia powder, 3 to 8 parts of silicon carbide powder, 12 to 15 parts of silicon nitride powder, 8 to 15 parts of modified attapulgite, 10 to 14 parts of clay, 5 to 10 parts of glass fibers, 3 to 10 parts of silicon oxide powder, 2 to 5 parts of graphene, 4 to 10 parts of concha haliotidis powder and 5 to 11 parts of sodium silicate. The invention further discloses a preparation method of the ceramic material. The high-performance ceramic material disclosed by the invention is wide in raw material sources and cheap in price of the raw materials, simple in preparation process and suitable for industrial mass production; the components in the high-performance ceramic material play the synergism, and the prepared ceramic material is far better both in compressive strength and flexural strength compared with the existing material, and broad in market prospects.

Description

technical field [0001] The invention relates to a ceramic material, in particular to a high-performance ceramic material. Background technique [0002] With the development of science and technology, various new materials have sprung up, and ceramic materials are one of them. Ceramic materials are a kind of inorganic non-metallic materials made of natural or synthetic compounds through molding or high-temperature calcination. There are many types of ceramics and different uses. With the development of modern science and technology, many new ceramic varieties have emerged in the past century, and structural ceramics are one of them. In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics due to their high toughness, high flexural strength, high wear resistance, excellent heat insulation performance, and thermal expansion coefficient close to steel. Mainly include: Y-TZP grinding balls, dispersing and grinding media, nozzles, ba...
