High-wear-resistance ceramic for diamond nozzle and preparation method for ceramic
High-wear-resistance ceramic for a diamond nozzle and a preparation method for the ceramic belong to the technical field of ceramic nozzles. The high-wear-resistance ceramic for the diamond nozzle comprises the following raw materials in percentage by weight: 90-95% of diamond micropowder, 1.5-4% of SiO2, 1-2.5% of B2O3, 0.5-1% of Al2O3, 0.5-1% of Na2O, 0.25-1% of K2O and 0.25-1.5% of Li2O, wherein the grain size of the diamond micropowder is 1-5 [mu]m. The preparation method for the high-wear-resistance ceramic for the diamond nozzle comprises the following steps of (1) preparing and uniformly mixing the raw materials according to the aforementioned percentage by weight, (2) preparing blanks, and (3) sintering the blanks to finally obtain the high-wear-resistance ceramic for the diamond nozzle. The ceramic is high in wear resistance, high in corrosion resistance, high in shape retention performance and long in service life. Not only is the replacing frequency of the nozzle reduced and the using efficiency of equipment improved, but also the wear resistance of the nozzle is improved. Moreover, the pollution on raw materials flowing through the nozzle due to the loss of the nozzle is reduced.
