NANOSCALE BARIUM TITANATE PARTICLES AND A PRODUCTION METHOD THEREFOR

摘要

The present invention relates to nanoscale barium titanate particles and to a production method therefor, and relates to an invention employing mixed beads such that uniform milling and a dispersing effect can be simultaneously achieved, and employing a method in which a BaCO3 starting material is milled on the nano scale and is then mixed with nanoscale TiO2 thereby allowing dispersion to be effected by means of a high-energy mill at a low speed of 1,600 rpm and 0.65 mm and 1 mm mixed beads in the first instance, and milling and dispersion to be carried out simultaneously by charging into linearly connected 0.1 mm and 0.3 mm nano-milling and dispersing high-energy mills. Also, the present invention relates to an invention in which, when the TiO2 starting material is used, a mixture of rutile (58.2%) and anatase (41.8%) is used such that a smooth diffusion pathway can be obtained, and such that the high degree of crystallisation of the rutile phase can be employed at the same time, such that higher reactivity and tetragonality (c/a) can be achieved than when using other starting materials which is to say a single rutile or anatase phase.
