The Classification Mechanism of ZrB2 Powder Materials via the Sedimentation Method
Abstract:
With the development of science and technology, the more and more demand of ultra-fine powder is showed. The ZrB2/A1(OH)3-Y(OH)3 core-shell composite particles already are synthesized. To obtain the better A1(OH)3-Y(OH)3 composite shell, the higher coating ratio on the ZrB2 particles surfaces to prepare high performance multiphase ceramics, the classification of ZrB2 raw material is investigated by the sedimentation method. The sedimentation time of classing ZrB2 particles is decided for 30 minutes to reach fine ZrB2 particles with smaller size and narrower distribution is obtained.
