High-corrosion-resistance composite ceramic material

Abstract

The invention discloses a high-corrosion-resistance composite ceramic material which is characterized by comprising the following components in parts by weight: 25-45 parts of zirconite, 31-55 parts of titanium corundum, 10-23 parts of zirconium silicate, 21-47 parts of Cangma soil, 5.5-13.7 parts of boron nitride, 1-10 parts of silicon dioxide, 5-19 parts of titanium mineral, 5-11 parts of borax, 1-8 parts of zirconium dioxide, 3-9 parts of manganese oxide, 1-4 parts of chrome oxide, 15-49 parts of magnesite, 0.5-3.7 parts of magnesium oxide, 11-28 parts of apatite, 5-27 parts of dolomite and 1-3 parts of alumina. The high-corrosion-resistance composite ceramic material has the advantages of small thermal expansion coefficient, low cost, high fire resistance, high thermal shock stability and high oxidation resistance, solves the waste residue pollution, saves the resources, solves the problem of industrial residue pollution discharge, thoroughly utilizes nitrogen and oxygen in air as fuels, saves the energy sources, and has the effects of energy saving and emission reduction.

Description

technical field [0001] The invention relates to a high corrosion resistance composite ceramic material. Background technique [0002] The high-temperature materials used in industrial ceramics, electric power, aviation, heavy metal smelting, ladle bottom blowing furnace, petroleum hot blast furnace and other processes have poor comprehensive performance, poor oxidation resistance and low refractoriness. Improper material selection will directly affect the service life, the porosity is too high, the thermal shock resistance is poor, the corrosion resistance is poor, and the Fe0 slag resistance is poor, which directly affects the profit of the enterprise and greatly wastes resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high corrosion resistance composite ceramic material. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present inventi...
