Embodiment Construction

[0004] With an average particle size of 60nm, use 3mol% of Y 2 o 3 Stable tetragonal polycrystalline zirconia powder is the main raw material. The above powder is added to a ball mill tank lined with alumina, and deionized water and zirconia ceramic balls are added at the same time (the weight ratio of deionized water: ball: powder =1:2:1,), using methyl cellulose (5%-10% of the total weight) as a dispersant, for ball milling. After ball milling for 16 hours, vacuum defoaming was performed. Then inject the slurry into a plaster mold to make a zirconia ceramic tableware wet blank, then demould, dry, and sinter in a high-temperature resistance furnace at 1550°C for 2 hours, then centrifugally polish for 4 hours, and finally finish machining to get Zirconia ceramic tableware with fine quality, round color, comfortable touch and good toughness. The slurry can also be made into a green body of zirconia ceramic tableware by gel injection molding.

Abstract

A zirconia ceramic dishware is characterized by tetragonal zirconia polycrystal ceramic powder added with 3 to 8 mol percent of yttria as stabilizing agent. The invention has the advantage that since zirconia ceramic which is hard and cannot be easily broken is chosen to produce the high-grade dishware, the invention overcomes the defect that ordinary ceramic dishware is easy to break.

Description

technical field [0001] The invention relates to a high-grade tableware, in particular to a zirconia ceramic tableware and a preparation method thereof. Background technique [0002] Ceramic tableware is bright and clean, easy to clean, and has been widely used by people since ancient times. However, ordinary ceramic tableware is relatively easy to break, and its ornamental and collection value is not high. Contents of the invention [0003] The present invention aims to break through the defect that ordinary ceramic tableware is easy to break, and selects relatively hard and unbreakable zirconia ceramics for use in the field of tableware, providing a safe, hygienic, durable, high-end zirconia tableware with high collection value . The present invention is realized through the following technical solutions: a zirconia ceramic tableware material, characterized by tetragonal zirconia polycrystalline ceramic powder added with 3%-8 mol% yttrium oxide as a stabilizer. A metho...
