Abstract
The invention discloses a wear-resistant and heat-resistant ceramic material for a nozzle. The wear-resistant and heat-resistant ceramic material is prepared from the following raw materials in parts by weight: 2-3 parts of nano-nickel powder, 20-26 parts of boron nitride, 2-3 parts of kieselguhr, 34-38 parts of silicon nitride, 1-2 parts of polytetrafluoroethylene, 40-50 parts of silicon micro-powder, 3-5 parts of glimmerton, 24-27 parts of mullite particles, 8-11 parts of superfine VC powder, 2-3 parts of sodium carbonate, a proper amount of deionized water, 3-4 parts of ethyl orthosilicate, a proper amount of ethanol and 4-6 parts of an adjuvant. The ceramic disclosed by the invention has extremely high hardness, good abrasive resistance and heat resistance, and nontoxicity, and is capable of greatly prolonging the service life of the nozzle and improving the production efficiency. Through use of the adjuvant disclosed by the invention, the surface smoothness, the abrasive resistance and the heat resistance of the ceramic can be increased.
Description
technical field [0001] The invention relates to the field of ceramic materials, in particular to a wear-resistant and heat-resistant ceramic material for nozzles and a preparation method thereof.
