Wear-resistant high hardness ceramic and processing technology

Abstract

The invention discloses a wear-resistant high hardness ceramic and a processing technology. The ceramic is prepared from the following raw materials in parts by weight: 13-16 parts of aluminum hydroxide, 21-26 parts of polycrystalline silicon, 33-42 parts of ferric oxide, 35-42 parts of celestite, 12-15 parts of graphite, 15-17 parts of indium, 20-55 parts of aluminum oxide, 14-29 parts of ceramicpowder, 8-15 parts of feldspar, 4-7 parts of clay, 5-10 parts of Soochow soil, 9-18 parts of zirconium oxide, 3-6 parts of zinc oxide, 2-4 parts of magnesium carbonate, 1-2 parts of crystal stones and 2.4-4.7 parts of spodumene. By adding zirconium oxide into the formula, the whole ceramic has the advantages of high toughness, high bending strength and high wear resistance, excellent heat isolating property, coefficient of thermal expansion close to that of steel and the like, and can meet the massive industrial demands. Compared with common ceramics, the ceramic has a wider application rangeand is suitable for more severe using environments, the whole processing method is simple, and the processing method is low in cost and worth being popularized.

Description

technical field [0001] The invention relates to the technical field of ceramic processing, in particular to a wear-resistant high-hardness ceramic and its processing technology. Background technique [0002] Due to the continuous development of ceramic science and technology. And the market's increasing demand for new ceramic products forces ceramic companies to continuously develop new products, and must consider the problems and impacts of product changes on the rational organization of the production process. In order to enhance adaptability, ceramic enterprises not only need to vigorously improve the application level of science and technology and the research ability of new products, and constantly update products, but also must adopt advanced production organization methods such as plan review method, group process and multi-variety mixed flow production. Adopt adaptable machinery and equipment and flexible manufacturing system to meet the needs of production changes....

Problems solved by technology

[0003] At present, ceramics can not only be used for decoration and storage, but many ceramic products can be used in industry. Traditional ceramics have poor wear resistance, and the processing methods are relatively backward, and the production efficiency is not enough. To solve these problems, here we propose a high wear resistance. Hardness Ceramics and Processing Technology
