preparation example Construction

[0038] The preparation method of above-mentioned zirconia ceramics, comprises the following steps:

[0039] Step S110, providing a zirconia ceramic raw material composition.

[0040] In one embodiment, the zirconia ceramic raw material composition is obtained by thoroughly grinding and mixing the raw materials of the zirconia ceramic main body material and the toning composition. Further, the grinding can be sand milling or ball milling. Furthermore, the ball milling is wet ball milling or dry ball milling.

[0041] In one embodiment, the toning composition is obtained by mixing a salt solution corresponding to each raw material with an alkali solution to carry out a precipitation reaction to obtain a precipitate and calcining it. Grinding and mixing the ceramic zirconia ceramic main body material and the toning composition thoroughly to obtain a zirconia ceramic raw material composition. Further, the alkali solution is sodium hydroxide solution. The salt solution is at le...

Embodiment 1

[0051] Get 98.999 parts of zirconia ceramic body material (containing 2.5% Y 2 o 3 , with a specific surface area of ​​18m 2 / g), add 0.001 part of CuO, 0.34 part of Al 2 o 3 , 0.01 part of CoO, 0.12 part of CeO2, 0.43 part of MgO, fully mixed and dispersed with a ball mill, dried the zirconia ceramic raw material composition, and granulated to obtain master batches. Use 100MPa cold isostatic pressing to form a flat plate, then raise the temperature to 1360°C at a rate of 2°C / min, and keep it warm for 1.5h to obtain zirconia ceramics.

Embodiment 2

[0053] Get 92.95 parts of zirconia ceramic host material (Y containing 7.85% mass fraction 2 o 3 , with a specific surface area of ​​12m 2 / g), add 5.0 parts of CuO, 0.48 parts of Al 2 o 3 , 0.96 Nd 2 o 3 , 0.66 parts of CaO were dispersed by wet ball milling, and dried to obtain a zirconia ceramic raw material composition. The zirconia ceramic raw material composition is mixed with polypropylene resin, stearic acid and common paraffin at 170° C. for 3 hours to obtain a premixture. The content of polypropylene resin in the premixture is 6%, and the content of stearic acid is 1.5% %, the content of ordinary paraffin is 7%. The premix is ​​injection molded. Raise the temperature at 0.1°C / min to 200°C, 0.4°C / min from 200°C to 400°C, hold at 400°C for 2 hours to remove the glue, and then rise to 1360°C at 2°C / min for 1.5 hours to obtain zirconia ceramics.

Abstract

The invention relates to a color matching composition, a zirconia ceramic raw material composition, a zirconia ceramic and a preparation method of the zirconia ceramic. The color matching compositionis used for adjusting the color of the zirconia ceramic and is characterized by comprising a first component, a second component and a third component; the first component is copper oxide, the secondcomponent is chosen from at least one of aluminum oxide, thulium oxide and neodymium oxide; the third component is chosen from at least one of cerium oxide, zinc oxide, calcium oxide, cobaltous oxide,magnesium oxide, strontium oxide, titanium oxide and praseodymium oxide, wherein the mass ratio of the first component to the second component to the third component is (0.001-5):(0.001-20):(0.001-20). The color matching composition can be applied to the sapphirine zirconia ceramic obtained in the zirconia ceramic.

Description

technical field [0001] The invention relates to a toning composition, a zirconia ceramic raw material composition, a zirconia ceramic and a preparation method thereof. Background technique [0002] my country has a history of thousands of years of making ceramics. In the formula of ceramic raw materials, the theory of using silicate and alumina as ceramic supports has been used for thousands of years. Chinese jade porcelain is created in the field of ceramics with its warm color and fine quality. Immortal myths, legends and brilliance. [0003] Chinese jade porcelain has a warm color and fine texture, but its whiteness is low and its light transmission is not ideal; bone ash china has high whiteness and good light transmission, but its color is relatively hard and its porcelain is rough. It is the pursuit goal of the ceramic industry to produce a kind of porcelain that combines the warm color and fine quality of Chinese jade porcelain with the high whiteness and high light t...
