Abstract： |
The invention discloses a barium titanate low-dimensional nano powder material and its preparation method, which comprises using commercially available super fine barium titanyl oxalate powder for barium titanate production as principal raw material, employing a hydrophobic agglomeration sorting floatation process, changing the relative proportion of the surface active agent and the organic solvent powder, and carrying out the procedures of surface active agent wet method ball grinding adsorption, organic solvent pulping, emulsified stratification, extraction separation, drying and heat treatment. |
