| titleOfInvention | Method for preparing nano zirconia by using spray granulator |
| abstract | The invention discloses a method for preparing nano zirconium oxide by using a spray granulator, and provides a method for preparing monodisperse nano zirconium oxide, which comprises the steps of preparing a gel system and a zirconium source solution through the heating and drying characteristics of the spray granulator to form micron-sized micro-particle gel, then soaking gel particles in ammonia water, drying the gel after the gel is completely discolored, and calcining at 800 ℃ for 4 hours to obtain nano zirconium powder with good performance. As for the traditional gel method process, the chemical gel is adopted, the method has the characteristics of small colloidal particles, easiness in reaction, cleaning, loading and transportation and the like, and the problem of nano powder agglomeration is fundamentally overcome by firstly gelling and then reacting in the process. |
