A method for preparing a transparent
yttrium oxide ceramic component through two-step pressure
sintering comprises the following steps that firstly,
ceramic powder is synthesized, wherein high-purity superfine
yttrium oxide nanometer
ceramic powder is prepared with a reverse
coprecipitation method; secondly, transparent
yttrium oxide ceramic is sintered, wherein the transparent yttrium nanometer
oxide ceramic is prepared with a two-step pressurized
spark plasma sintering technology; thirdly, aftertreatment is carried out, wherein after
spark plasma sintering, a sample is taken out for annealing and
grinding polishing, and the final finished product, namely, the transparent yttrium
oxide ceramic component, is obtained.According to the method for preparing the transparent yttrium
oxide ceramic component through two-step pressure
sintering, the nanometer yttrium oxide
powder with a
small particle size and uniform distribution is prepared in advance with the reverse
coprecipitation method, and then the transparent yttrium oxide ceramic component good in compactness, uniform in particle size and good in performance is prepared with the two-step pressurized
spark plasma sintering technology.The strength of the prepared transparent yttrium oxide ceramic component is higher than 400 MPa, and the transparence is higher than 60%.
