| Abstract: | The rare -earth -zirconium composite oxides which have high thermal stability and high storage of oxygen are getting more and more attention in the automotive exhaust cleaning field. We explored the opti- mal way to prepare the large grain of rare -earth composite oxide, though the selection of best precipitator, best way to deposition etc. |
