High-temperature resistant ceramic material and preparation method thereof
The invention discloses a high-temperature resistant ceramic material and a preparation method thereof. The high-temperature resistant ceramic material is prepared from the following components in parts by weight: 55-60 parts of Si3N4, 12-16 parts of ZrO2, 11-13 parts of PVA, 6-8 parts of CuO, 5-12 parts of Al2O3, 5-8 parts of Nb2O5, 5-6 parts of WO3 and 3-5 parts of Pb3O4. The invention further provides a preparation method of the high-temperature resistant ceramic material. The preparation method of the high-temperature resistant ceramic material comprises the following steps: (1) weighing 55-60 parts of Si3N4, 6-8 parts of CuO, 5-12 parts of Al2O3, 5-8 parts of Nb2O5, 5-6 parts of WO3 and 3-5 parts of Pb3O4, ball-milling for 1-2 hours, and drying; (2) adding 11-13 parts of PVA and 12-16 parts of ZrO2 into a product obtained in the step (1) in sequence in an inert atmosphere, increasing temperature at the speed of 10 DEG C per minute, and heating the mixture at the temperature of 700-800 DEG C for 0.5-1 hour; and (3) pressing and molding a product obtained in the step (2) at the pressure of 6Mpa, and sintering the molded product at the temperature of 1,180-1,210 DEG C for 2-3 hours to obtain the high-temperature resistant ceramic material.
