Claim Text:
1. A method for producing a silicon-containing zirconia sintered body with a monoclinic phase comprising: wet mixing a mixture to obtain a mixed slurry, with the mixture including a silicon-containing zirconia powder, a sodium carbonate powder, a tetraethoxysilane solution, and an adhesive; drying the mixed slurry to obtain a caked mass, with the caked mass formed by bonding the silicon-containing zirconia powder and the sodium carbonate powder with the adhesive; grinding and sieving the caked mass to obtain a mixed powder; pressurizing and shaping the mixed powder to obtain a blank; calcining the blank in an environment at 900-1200° C. to obtain a silicon-containing zirconia calcined body; and sintering the silicon-containing zirconia calcined body 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%.
