Nanocrystalline spherical oxide ceramics, synthesis and use method thereof

摘要

Nanocrystalline spherical oxide ceramics, the present invention relates to the use and synthesis method thereof. In addition to having a nano-crystalline and spherical form, the supplemental feature of the series, ie, particle size of 40μm below, these oxides obtained by the explosive water-in-oil emulsion (W / O) is bimodal I show sex particle size distribution, high purity, the crystal phase and stable solution aggregation. Because of the characteristics of this series, the powder of these, it is particularly suitable for some applications the coating process, the near-net-shape process, etc., by using the ceramics industry, they, mechanical resistance is high very high I bring the ceramic body of porous in density.
