Abstract

The invention discloses a zirconia ceramic piece. The zirconia ceramic piece is prepared by employing zirconia as a main raw material and through a ceramic production technological process. Correspondingly, the invention also discloses a preparation method of the zirconia ceramic piece. The preparation method includes the steps: carrying out dry pressing molding and isostatic pressing molding of the main raw material for preparing the zirconia ceramic piece to obtain a piece green body; carrying out high-temperature sintering of the molded green body in an electric furnace with the high-temperature sintering temperature of 1400-1600 DEG C; processing the sintered green body with a piece pattern by an ultrasonic technology; painting a ceramic glaze on the pattern on the surface of the green body; carrying out glaze firing of the glazed green body; and grinding flatly and polishing the glaze-fired green body to obtain the zirconia ceramic piece product. By adopting the preparation method, the zirconia ceramic piece is glittering, translucent, bright, high-grade and elegant, has high degree of finish, jade texture, compact structure, high strength and high hardness, and creates a new piece species.

Description

technical field [0001] The invention relates to the technical field of sports and entertainment products, in particular to a zirconia ceramic chess piece and a preparation method thereof. Background technique [0002] Chess pieces are cultural equipment with entertainment and intellectual development, the main types include Chinese chess, chess, go, shogi, backgammon or flying chess and so on. Above-mentioned chess piece is widely used, and is deeply liked by the public. Chinese chess, in particular, has a long history in China and is a kind of confrontational game between two players. The mass base of Chinese chess is quite broad, and people can often be seen playing chess in the streets and alleys, parks, work units, schools and various activity venues. [0003] Traditional Chinese chess is generally made of wood and plastic. Patent CN1590242 discloses a kind of jelly Chinese chess. The jelly packaging shell is printed with the names of Chinese chess pieces, which solve...
