Problems solved by technology

However, due to the very high sintering temperature of special ceramic materials, especially the sintering temperature of zirconia ceramic materials is higher than 1300°C in almost all cases, and most of the pigments have very poor high-temperature stability, and can only stabilize coloring at about 1200°C. It greatly limits the development of colored zirconia ceramics and cannot meet people's individual needs

Abstract

The invention relates to a method for preparing powderblue zirconia ceramics and prepared products. The method comprises: adopting superfine zirconia ceramic powder as base powder, adding industrial metal oxide including cobalt oxide, silicon dioxide, alumina, vanadium pentoxide and magnesia, and obtaining the powderblue zirconia ceramic products after weighing, ball milling, drying, sieving, mixing, injection, solvent degreasing, thermal degreasing, sintering, rough machining, finish machining and polishing, wherein the sintering temperature is between 1,430 and 1,480 DEG C, and the temperature preservation time is 180 minutes. The obtained products are bright-colored and stable, and can be widely applied in the fields of zirconia ceramic watches, zirconia ceramic ornamental articles and the like.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), in particular to a preparation method of pink-blue zirconia ceramics applied to watch accessories and jewelry and the prepared product Background technique [0002] With the development of the times, the timing function of watches is gradually being weakened, and the decorative function with clothing is gradually occupying a dominant position. High-performance colored zirconia ceramic watch accessories and jewelry products are characterized by their high hardness, wear resistance and toughness. Good quality, long-lasting color, no damage to the skin, high insulation, no metal and electroplating pollution, etc., are deeply loved by fashionable women. With the continuous enrichment of zirconia ceramic colors, it is bound to affect the development trend of watches and jewelry. However, due to the very high sintering temperature of special ceramic materials, especially the s...
