  • Methods for producing a silicon-containing zirconia calcined body and a silicon-containing zirconia sintered body
    Patent number: 9522848
    Abstract: A method for producing a silicon-containing zirconia calcined body includes wet mixing a mixture to obtain a mixed slurry, with the mixture including a silicon-containing zirconia powder, a sodium carbonate powder, a tetraethoxysilane, and an adhesive; drying the mixed slurry to obtain a caked mass; grinding and sieving the caked mass to obtain a mixed powder; pressurizing and shaping the mixed powder to obtain a blank; and calcining the blank in an environment at 900-1200° C. to obtain a silicon-containing zirconia calcined body. The silicon-containing zirconia calcined body can be sintered at 1415-1450° C. into a silicon-containing zirconia sintered body, with a shrinkage ratio during sintering the silicon-containing zirconia calcined body into the silicon-containing zirconia sintered body being 22-31%.
