Manufacturing method of water-permeable zirconia ceramic matrix and ceramic matrix thereof

Abstract

The invention relates to the technical field of new materials, in particular to a manufacturing method of a water-permeable zirconia ceramic matrix, the manufacturing method comprises the following steps: (1) obtaining a zirconia blank and putting the zirconia blank in a sintering furnace; and (2) adjusting the sintering temperature and the corresponding time, and controlling the void ratio of the product to obtain the ceramic matrix with the sintering density of 97.5-98% and the porosity of 1-1.5%. The novel water-permeable zirconia ceramic matrix which is high in strength and easy to color can be produced without a ball-milling granulation process. In addition, the invention also provides a ceramic matrix with the sintering density of 97.5-98% and the porosity of 1-1.5%.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a method for making a water-permeable zirconia ceramic base and the ceramic base. Background technique [0002] At present, zirconia ceramic materials have been widely used in high-tech and basic industrial fields. Except for ceramic knives in the civilian field, there are no other application examples at home and abroad. It is understood that there is a huge market demand for civilian handicrafts at home and abroad, but the products and materials are single. [0003] The traditional coloring of ceramic materials is to use wet chemical method plus physical method or physical solid phase method to process powder first. The process of wet chemical method plus physical method is more complicated and inconvenient for production. The physical solid phase method and its drawbacks are as follows: [0004] A) The physical solid-phase method color matching process is to mix the zi...

Problems solved by technology

[0004] A) The physical solid-phase method color matching process is to mix the zirconia powder and the pigment ball mill and then perform calcination and granulation treatment. Since the calcination temperature inside the calcination furnace is affected by the air pressure and environment, there will be a certain degree of high and low deviation. Causes the difference in the performance index of the coloring powder and the color difference. In addition, affected by the above factors, it is difficult to achieve uniformity in the raw material index of each batch of calcined treatment, which directly affects the consistency of the fired product.

[0005] B) After the coloring powder is processed by coloring ingredients, it will pollute the ball mill, granulator and other equipment and circulation pipelines, which not only greatly increases the workload of equipment cleaning, but also easily pollutes the raw materials in the subsequent powder making, resulting in product scrapping

[0006] C) The green body pressed by the colored raw material is easy to lose the color brightness during the sintering process and pollute the sintering furnace

[0007] D) The color matching process has a large workload and many processes, which wastes manpower, material resources and energy
