| titleOfInvention | A kind of new method for preparing dental nano zirconium oxide powder |
| abstract | The present invention provides a kind of new method for preparing dentistry nano zirconium oxide powder, its step includes：It is raw material to select soluble zirconium oxychloride, and soluble yttrium salt generates zirconium oxide presoma with vigorous stirring as precipitating reagent as stabilizer, ammonium hydroxide using Rapid coprecipitation method；It is not required to be aged, is diluted immediately with a large amount of deionized waters, then through filtering, wash, be dehydrated, after drying, calcining obtains Zirconium powder.The nano zircite crystal habit that this method provides is tetragonal phase zirconium oxide particulate, and particle size primary particle average grain diameter is 2 3nm, and after 800 DEG C handle 2h, particle size is 10nm and 25nm.The method of the present invention preparation process simple and convenient, cost is relatively low, and the cycle is short, reproducible, suitable for mass production, and powder granularity is uniform, is nanoscale. |
