Abstract

The invention discloses a high-toughness ceramic nozzle material which is composed of, by weight parts, 70-75 parts of silicon nitride, 26-32 parts of boron nitride, 13-17 parts of nano silicon carbide, 10-14 parts of magnesium fluoride, 18-22 parts of chromium carbide, 15-19 parts of aluminum oxide, 13-17 parts of titanium diboride, 5-8 parts of kaolin, 3-6 parts of halloysite, 1-5 parts of light calcium carbonate, 9-13 parts of magnesium oxide, 1-3 parts of water glass, 5.3-6.0 parts of butyl acetate, 3.5-4.8 parts of carboxymethyl cellulose and 0.8-1.6 parts of lead naphthenate. The invention further discloses a method for preparing the high-toughness ceramic nozzle material. A prepared ceramic nozzle is high in intensity and good in toughness, the deformation resistance of the ceramic nozzle can be greatly improved, the density is high, the washing resistance of the nozzle is improved, and the service life of the nozzle is prolonged.

Description

technical field [0001] The invention relates to the technical field of ceramic nozzles, in particular to a high-toughness ceramic nozzle material and a preparation method thereof. Background technique [0002] Amorphous magnetic ring is a magnetic element processed by amorphous material. According to the material of the amorphous strip used, it can be divided into iron-based amorphous, cobalt-based amorphous and so on. According to the shape of the material, it can be divided into strip type magnetic ring and powder type magnetic ring. The characteristic saturation magnetic density of the amorphous magnetic ring is much higher than that of ordinary ferrite and powder magnetic cores. Amorphous magnetic ring, or metallic glass, is a new type of material that came out in the 1970s. It is formed by using rapid cooling technology to form molten steel into a thin strip with a thickness of 30 microns, and then wind the thin strip. [0003] In the process of amorphous magnetic ri...
