▎ 摘 要
NOVELTY - High temperature resistant ceramic comprises 20-25 pts. wt. zircon, 18-20 pts. wt. zirconium boride, 15-20 pts. wt. asphalt, 12-15 pts. wt. flint clay, 10-15 pts. wt. purple clay, 10-15 pts. wt. alumina, 5-10 pts. wt. sodium silicate, 2-5 pts. wt. cerium oxide, 2-5 pts. wt. nano molybdenum oxide, 2-5 pts. wt. graphene, and deionized water. USE - High temperature resistant ceramic. ADVANTAGE - The high temperature resistant ceramic is heat-resistant at higher than 4000 degrees C, has good bending strength, and has improved quality. It has reasonable and simple preparation process and has reduced production costs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high temperature resistant ceramic by calcining zircon, flint clay and alumina at 550-600 degrees C for 0.5-1.0 hours; crushing and sieving through 70-80 meshes sieve; putting sieved powder into ball; adding graphene; ball milling for 1500-2000 revolutions per minute for 0.5-1.0 hour; drying; crushing to obtain particles I; calcining zirconium boride, purple clay, sodium silicate, and cerium oxide at 450-500 degrees C for 1.2-1.5 hours; crushing; sieving through 80-90 meshes sieve and adding into ball mill; adding asphalt; ball milling at 1500-2000 revolutions per minute for 0.5-1.0 hour; drying and crushing to obtain particles II; putting particles I and particles II; adding nano molybdenum oxide; ball milling at 6000-6500 revolutions per minute for 10-20 minutes to obtain composite ultrafine powder; spraying ultrafine powder with deionized water; stirring for 10-15 minutes; molding at 320-350 MPa; pre-calcining at 1500-1800 degrees C for 3-4 hour; and calcining at 2300-2500 degrees C for 7.5-8.5 hours.
