Ultrafine Zirconia Powder

Posted by RachelHJM on May 10th, 2017

In nanometer ceramic, the melting point, sintering temperature and crystallization temperature of ultrafine zirconia powder are lower than conventional powder. The particle size of nanometer ultrafine zirconia powder is small and surface energy is great, the interface after compressed to piece has high energy that can become driving force of atomic motion in the sintering process. So that ultrafine zirconia powder is advantageous to shrinkage of pore in the interface, which reduce the sintering temperature. The applications of nanometer ZrO2 are focused in structural ceramics, the oxygen sensor and catalyst promoter. Ultrafine zirconia enjoys superior plasticity and variable toughness, ultrafine zirconia is widely used in electrochemical devices, structural ceramics and catalytic system, etc. In the auto industry, nanometer ZrO2 catalyst is an important catalyst Promoter in catalytic converter system. Nanometer ZrO2 can help to control redox reaction of CeO2 catalyst carrier.
