CN112778799B discloses a preparation method of purple zirconia ceramics, which comprises the steps of firstly synthesizing purple pigment particles, wherein the purple pigment particles comprise a chromogenic core particle and an out-of-phase coating layer coated on the outer wall of the chromogenic core particle. The preparation of the purple pigment particles needs to be synthesized by two times of calcination, the synthesized purple pigment particles are added into a zirconia matrix, and the purple ceramic is obtained by sintering at high temperature after injection molding. The method comprises the steps of firstly synthesizing purple color development core particles, then carrying out-phase coating, obtaining a purple pigment through twice calcination, and then mixing, molding and sintering the purple pigment and zirconia powder to obtain the purple ceramic. The method has more working procedures, more complex preparation process and difficult control of the coating uniformity.
Therefore, it is urgently needed to provide a purple ceramic with higher cost performance and simple preparation process to meet the market demand.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the purple ceramic and the preparation method and the application thereof; the purple ceramic has the advantages of uniform color, bright color, certain impact resistance, simple preparation method, low cost and higher cost performance.
In order to realize the purpose, the technical scheme adopted by the invention is as follows:
the purple ceramic comprises the following preparation raw materials in percentage by mass: 2-5% of red pigment and CoAl2O40.01-0.1% and 94.9-97.9% of zirconia powder; in the red pigment, the mass ratio of the silver source to the zirconium source is (2-8): (92-98); the silver source is at least one of silver nitrate and silver acetate, and the zirconium source is at least one of zirconium hydroxide and zirconium oxyhydroxide.
CoAl2O4Has strong coloring ability, and when the addition amount of the red pigment is less than 2 percent, the red phase is easily coated with CoAl2O4Covering, wherein the obtained ceramic is blue ceramic, and purple ceramic with uniform color development cannot be obtained; when the addition amount of the red coloring material is more than 5%, the red coloring material is mixed with CoAl2O4Matching color matching can make the brightness value of the ceramic lower and the displayed color is bluish black. Furthermore, redThe content of the silver source in the pigment is too small, the silver content in the zirconium oxide which is calcined and dissolved is too low, and the red phase can not be displayed, and when the addition amount of the silver source is too high, the free silver can be increased, so that color spots are gathered after the purple ceramic is sintered. Preferably, the zirconium source is zirconium hydroxide, which has relatively high activity and can reduce the difficulty of solid solution of silver in zirconium.
Preferably, the purple ceramic comprises the following preparation raw materials in percentage by mass: 2.5-4.5% of red pigment and CoAl2O40.02-0.08% and 95.5-97.4% of zirconia powder; in the red pigment, the mass ratio of the silver source to the zirconium source is (2.5-8): (92-97.5). By optimizing the proportion of the components, the prepared purple ceramic does not show a red phase or a blue phase and has good impact resistance.
Further preferably, the purple ceramic comprises the following preparation raw materials in percentage by mass: 2.5-4% of red pigment and CoAl2O40.04-0.08% and 96-97.4% of zirconia powder; in the red pigment, the mass ratio of the silver source to the zirconium source is (6.5-8): (92-93.5). By further optimizing the content of each component, the ceramic can be made dark purple and have more brilliant color.
In addition, the invention also discloses a preparation method of the purple ceramic, which comprises the following steps:
(1) mixing a silver source and a zirconium source, carrying out ball milling on the mixture to form slurry, carrying out spray granulation, and calcining the slurry in vacuum or reducing atmosphere to obtain a red pigment;
(2) mixing red pigment and CoAl2O4Adding the mixture into zirconia powder, ball-milling to form slurry, spraying, granulating and forming to obtain a green body, and sintering in vacuum or reducing atmosphere to obtain the purple ceramic.
Preferably, in the step (1), the calcining temperature is 900-1200 ℃ and the time is 1.5-3 h; in the step (2), the sintering temperature is 1300-1500 ℃, and the time is 2-3 h.
The red pigment powder has overhigh hardness due to overhigh calcining temperature and overlong heat preservation time, the granularity is difficult to be levigated during subsequent ball milling, and the preparation cost of the powder is increased; and the calcining temperature is too low, the heat preservation time is too short, the silver solid solution degree is not enough, and the color development of the red pigment is not obvious.
The purple ceramic has the advantages that the sintering temperature is too high, the heat preservation time is too long, the formed ceramic is easy to deform, the subsequent further mechanical processing is not facilitated, and the color is dispersed too fast in the sintering process, so that the chromaticity distribution is uneven; the sintering temperature is too low, the heat preservation time is too short, the ceramic cannot be sintered and compact, the color uniformity is poor, the ceramic cannot be fired, and the ceramic is fragile. When the sintering temperature falls within the above range, the relative density of the ceramic is high and has good impact resistance.
Preferably, the sintering temperature of the purple ceramic is 1350-1430 ℃. When the sintering temperature is in the range, the color saturation of the finished porcelain is moderate, the finished porcelain has good texture and jade texture.
Preferably, in the step (1), after the slurry is ball-milled, the particle size of D50 in the mixture is 0.2-0.4 μm; in the step (2), after ball milling and slurrying, the D50 particle size of the mixture is 0.2-0.3 μm. In the step (2), the forming method is one of dry pressing, injection molding and tape casting. The particle size is selected to improve the uniformity of the color of the ceramic and to improve the strength and corrosion resistance of the ceramic.
Meanwhile, the invention also discloses application of the purple ceramic in the fields of home decoration, intelligent equipment and electronic components.
Compared with the prior art, the invention has the beneficial effects that: according to the invention, by selecting the raw materials for preparing the ceramic, the uniform color development of the ceramic can be ensured; by optimizing the proportion of the components, the purple and dark purple ceramics which do not show red phase and blue phase can be prepared, the requirements of the public on the color and luster are met, and the color and luster of the ceramics has good stability and does not change color for a long time. In addition, the ceramic has low cost of preparation raw materials, high cost performance and simple preparation method, and is suitable for industrial production.

Comparing the formulation and test results of example 5 and comparative example 4, it was found that the amount of the red colorant was too large, the L value, the a value and the b value were significantly changed, and the ceramic was bluish-black.
Comparing the formulation of example 4 with comparative examples 5 and 6 and the results of the tests, it can be seen that CoAl2O4Below the lower limit of the invention, red ceramics are obtained; above the upper limit of the invention, dark blue ceramics are obtained.
In addition, as shown in the test results of comparative examples 15 to 19 and comparative examples 7 to 8, it can be seen that the sintering temperature of the ceramic has a great influence on the appearance and impact resistance of the ceramic. When the sintering temperature is 1350-1420 ℃, the color saturation of the finished porcelain is moderate, the finished porcelain has good texture and jade texture, and the impact strength can reach more than 30 cm. When the sintering temperature is lower than 1300 ℃, the porcelain cannot be fired and is fragile, when the sintering temperature is higher than 1500 ℃, the pigment is diffused too fast in the sintering process, so that the chromaticity distribution is uneven, the impact strength of the porcelain and the pigment is below 25cm, and the mechanical property is poor.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
