Abstract

The invention relates to a pink yttrium-zirconium structural ceramic and a preparation method thereof, belonging to the technical field of structural ceramics. Pink yttrium-zirconium ceramics are composed of 4.8-5.5%Y2O3, 92-96%ZrO2, 0.1-0.8%Nd2O3, 0.5-4.0%Er2O3, 0.05-0.50%La2O3, 0.1-0.30%Sc2O3; pink yttrium-zirconium structural ceramics preparation The method is batching-precipitation-washing-press drying-pink yttrium-zirconium ceramic powder precursor-burning-vibration milling-jet milling-spray granulation-dry pressing molding (or injection molding).

Description

technical field [0001] The invention relates to a pink yttrium-zirconium structural ceramic and a preparation method thereof, belonging to the technical field of structural ceramics. Background technique [0002] As we all know, at present, the color of zirconia ceramic products at home and abroad is single, only white and black, and the ceramic artwork is only the surface glaze color is pink, but the embryo body is not pink, and the domestic industry and civilian use are pink YZr structure Ceramic products have not been reported. Contents of the invention [0003] In order to overcome the deficiency that the current zirconia ceramic products only have black and white colors, the present invention provides a pink yttrium-zirconium structure ceramic and its preparation method. The technical solution adopted by the present invention to solve its technical problems is: a kind of pink yttrium-zirconium structure ceramic is made of 4.8-5.5%Y 2 o 3 , 92-96% ZrO 2 , 0.1-0.8% ...
