Problems solved by technology

However, at present, domestic daily-use ceramics are made of ordinary ceramics, which cannot meet the requirements of high-grade porcelain at all, and because ordinary ceramics have low strength, poor wear resistance, and poor toughness, they are easy to be broken, so it is difficult to Upscale, so it is necessary to improve this

Embodiment

[0009] The preparation method of the zirconia ceramic product in this embodiment is described by taking the zirconia tea set for daily use as an example.

[0010] A zirconia tea set for daily use, using high-density zirconia powder injection molding, high-density zirconia nano-powder, yttrium trioxide and polyethylene, according to 90 parts of zirconia powder, 7 parts of polyethylene, 3 parts of diyttrium trioxide Weigh the proportion of yttrium, then put it into the internal mixer and heat it to 170°C for mixing. The mixed material is placed in the injection molding machine, and then injected into the mold at a temperature of 170°C and a pressure of 90MPa, and cooled After solidification, the green body can be obtained by demoulding; then the green body is put into the furnace for heating to remove the organic binder in the green body, that is, degreasing; then in the high-temperature furnace, the green body is put into the sintering furnace, Vacuumize, fill with nitrogen...

Abstract

A preparation method of zirconium oxide ceramic products adopts zirconium oxide powder as a raw material to make the zirconium oxide ceramic products, and comprises the following steps: mixing high-density zirconium oxide powder with a stabilizer and a binder, carrying out injection molding on the above obtained mixture, carrying out injection molding in a mold at a certain temperature under a certain pressure, cooling for solidification, demolding, and sintering the above obtained green bodies at a high temperature under a high pressure to obtain the zirconium oxide ceramic products with high strength and high toughness. The zirconium oxide ceramic products have the advantages of high strength, good wear resistance, high toughness, and unlikely breaking.

Description

technical field [0001] The invention belongs to the technical field of ceramic products, and in particular relates to a preparation method of zirconia ceramic products. Background technique [0002] Ceramic products have been widely used by people since ancient times and have been deeply loved by people. However, ordinary ceramic tableware is relatively easy to break, and its ornamental and collection value is not high. Now people's demand for high-grade ceramic products is increasing, especially for households and exports with middle-income and above, and the demand for products is increasing year by year. However, at present, domestic daily-use ceramics are made of ordinary ceramics, which cannot meet the requirements of high-grade porcelain at all, and because ordinary ceramics have low strength, poor wear resistance, and poor toughness, they are easy to be broken, so it is difficult to Upscale, so it is necessary to improve this. [0003] On the other hand, zi...
