Abstract

The invention provides composite stable microcrystal zirconium oxide ceramic mixed powder and a manufacturing process. Industrial-grade zirconium oxide powder is used as a main material and a suitable amount of cerium oxide (CeO), yttrium oxide (Y2O3), aluminum oxide and calcium carbonate (CaCO3) are used as stabilizing agents; all the components are prepared according to the following percentage by weight: 10-12% of the cerium oxide (CeO), 1-2% of the yttrium oxide (Y2O3), 3-8% of the aluminum oxide (Al2O3), 1-2% of the calcium carbonate (CaCO3) and the balance of the industrial-grade zirconium oxide powder; and the powder materials are mixed according to the proportion and the composite stable microcrystal zirconium oxide ceramic mixed powder is prepared by the steps of physically mixing, super-thinning, calcining, dispersing and granulating. With the adoption of a plurality of the stabilizing agents, the stable composition of zirconium oxide is realized, and zirconium oxide ceramic which is stably composited has better physiochemical performances.

Description

technical field [0001] The invention relates to a non-metallic material formula and a production process thereof, in particular to a microcrystalline zirconia ceramic production formula and a production process, belonging to the technical field of new materials. Background technique [0002] Zirconia ceramics are a new type of ceramics that have emerged in recent decades. Zirconia ceramics are widely used due to their high toughness, high bending strength, high wear resistance, excellent heat insulation performance, and thermal expansion coefficient close to steel. Applied in the field of structural ceramics. Mainly include: Y-TZP grinding balls, dispersing and grinding media, nozzles, ball valve cores and ball seats, zirconia molds, micro fan shafts, optical fiber pins, optical fiber sleeves, drawing dies and cutting tools, wear-resistant knives, Cases and straps, golf light bats and other wear-resistant parts at room temperature, etc. In addition, because zirconia cerami...
