  • Titanium nitride-reinforced zirconia toughened alumina ceramic powder and preparation method thereof
    Patent number: 11345638
    Abstract: The present invention provides titanium nitride-reinforced zirconia toughened alumina (ZTA) ceramic powder and a preparation method thereof, and belongs to the technical field of ceramic materials. The preparation method provided in the present invention includes the following steps: mixing an aluminum salt, a zirconium salt, a yttrium salt, and a titanium salt with water to obtain a mixed aqueous solution, where the aluminum salt, the zirconium salt, the yttrium salt, and the titanium salt are water-soluble inorganic salts; mixing the obtained mixed aqueous solution and an alkaline precipitant for precipitation, to obtain hydroxide precipitate powder; successively conducting first calcination and second calcination on the obtained hydroxide precipitate powder, to obtain oxide solid solution powder; and subjecting the obtained oxide solid solution powder to selective nitridation reaction, to obtain titanium nitride-reinforced ZTA ceramic powder.

  • Al2O3—ZrO2—Y2O3—TiN nanocomposite ceramic powder and preparation method thereof
    Patent number: 11332408
    Abstract: The present invention provides an Al2O3—ZrO2—Y2O3—TiN nanocomposite ceramic powder and a preparation method thereof, and belongs to the field of ceramic materials. In the ceramic powder provided by the present invention, a molar ratio of Zr:Al:Y:Ti is (30-70):(10-30):(0.4-1):(5-20). The nanocomposite ceramic powder provided by the present invention is good in dispersibility, and does not generate agglomeration, and the mechanical properties of a ceramic material obtained after sintering of the nanocomposite ceramic powder provided by the present invention are better. Proved by results of embodiments, the hardness of a ceramic material obtained by sintering of the nanocomposite ceramic powder provided by the present invention is 28-35 GPa, and abrasion ratio is 4500-6000:1.
