Abstract
The invention discloses a ceramic material and a preparation method thereof, belonging to the technical field of ceramic materials. The ceramic material disclosed herein comprises 80-90wt% of alumina, 5-15wt% of zirconia, 0.5wt% of yttrium oxide, and 3wt% of zinc oxide. According to the invention, by adding yttrium oxide and zinc oxide in the ceramic material, the strength of the ceramic material can be raised, and the advantages of good wear resistance, high toughness, and the like are achieved.
Description
Technical field
The present invention relates to technical field of ceramic material, be specifically related to a kind of stupalith and preparation method thereof.
Background technology
Stupalith is with one type of ceramic natural or that the synthetic compound process is shaped and high temperature sintering is processed.It has advantages such as HMP, high firmness, high-wearing feature, antioxidant.Can be used as structured material, cutter material,, can be used as functional materials again because pottery also has some special performances.
Summary of the invention
The object of the invention is according to deficiency of the prior art a kind of stupalith to be provided.
Another purpose of the present invention is to provide the preparation method of above-mentioned stupalith.
Above-mentioned purpose of the present invention is achieved through following technical scheme:
A kind of stupalith is processed by following raw material according to weight percentage: aluminum oxide 80 ~ 90%, zirconium white 5 ~ 15%, yttrium oxide 0.5%, zinc oxide 3%.
As a kind of preferred version, stupalith according to the invention is processed by following raw material according to weight percentage: aluminum oxide 85%, zirconium white 11.5%, yttrium oxide 0.5%, zinc oxide 3%.
As a kind of preferred version, the median size of said aluminum oxide is 0.15 ~ 0.2 micron, and purity is 99.9%.
The preparation method of stupalith according to the invention is with each raw material grinding powder, mixes the back granulation, is molded into base substrate then, and sintering obtains stupalith.
Embodiment
Come further to explain the present invention below in conjunction with embodiment, but embodiment does not do any type of qualification to the present invention.
Embodiment 1
Take by weighing raw material (kg) according to prescription:
Aluminum oxide 85, zirconium white 11.5, yttrium oxide 0.5, zinc oxide 3.
With each raw materials mix, put into the polyvinyl alcohol solution of 25kg 7%, place ball grinder, ball milling 10h, the solution that obtains mixing; Form blockly with solution is dry, be crushed into powder, watering is granulated on powder, obtains ceramic powder after crossing 150 mesh sieves, is pressed into base substrate again, obtains ceramic body.
Claims (4)
