(1) each component is taken according to the weight percent of following batching:
Zirconium white 86-92 %
Yttrium oxide 3-8.5 %
Calcium oxide 2-4 %
Magnesium oxide 2-5 %
Cerium oxide 0.5-3%;
(2) zirconium white taken, yttrium oxide, calcium oxide, magnesium oxide, cerium oxide are mixed, with chemical coprecipitation method material, electric baking oven put into by the powder made, toast 24 hours at 120 DEG C of temperature, after toasting, powder loads ball mill, corundum 95 porcelain ball is added by the weight loading powder, the ratio of powder and porcelain ball is 1:1, the corundum 95 porcelain ball added is in sphere diameter 5mm ratio 20%, 20mm ratio 50%, 50mm ratio 30%, ball milling 32 hours, get the test of powder sample, its granularity is less than 0.3 micron;
(3) by the discharge of fine material after ball milling, weighing joins in low rate mixing machine, add again the paraffin of 8%, the beeswax of 1% and 0.03% oleic acid, the temperature of low rate mixing machine is set to 65 DEG C, heats 1 hour, after paraffin and beeswax fully melt, start low rate mixing machine to stir, stir 2 hours in the environment of temperature 65 DEG C, the slip after fully stirring is put into stainless steel vessel, make gatch after slip cooling, obtain stablizer compound zirconium oxide powder.
The present invention has following beneficial effect:
1, with Ceo
2and Y
2o
3jointly as stablizer, can stabilising effect be strengthened, suppress Zro
2phase transformation, slows down low temperature degradation phenomena.
2, the Al of high elastic coefficient and high strength is mixed
2o
3its hot strength can be made to be improved, to add one package stabilizer (Y
2o
3+ Cao+Mgo+Ceo
2), strict control respective content, purity and granularity, ensure its homogeneity in powder, greatly enhance stabilising effect.
3, add above-mentioned one package stabilizer raw material, particle fineness must be made to reach the critical particle size of crystal transition, stablizer will be made simultaneously fully to mix with Zirconium powder, general complete processing is difficult to reach production high-quality zirconium powder.
