摘要： The invention provides a method for producing barium titanate-based particulate compositions. The method includes a heat treatment step, separate from a sintering step, that involves treating a barium titanate-based particulate composition at a temperature between about 700° C. and about 1150° C. to increase average particle size. The increased average particle size can improve the electrical properties (i.e., dielectric constant and dissipation factor) of the heat-treated composition as compared to the composition prior to heat treating. The heat-treated composition may be further processed, for example, by producing a dispersion which may be cast and sintered to form a dielectric layer in electronic components including MLCCs.

摘要： A barium titanate powder has an average particle size ranging from 0.1-1.0 &mgr;m, a CV value (standard deviation of the particle size/the average particle size) of the particle size distribution being 40% or less, and a zeta-potential ranging from −30 to −60 mV measured by a laser Doppler method using electrophoresis at pH 6.4. The barium titanate powder is presintered at a temperature ranging from 900 to 1200° C. The barium titanate powder has superior dispersion characteristics in slurrying, and is capable of partly inhibiting agglomeration of the barium titanate after sintering. It is therefore suitable as materials for dielectric layers of multilayer ceramic capacitors. In particular, the barium titanate has a sintered density of 95% or more of the theoretical density thereof, and the dielectric constant is 4000 or more.
摘要翻译：钛酸钡粉末的平均粒径为0.1〜1.0μm，粒径分布的CV值（粒径/平均粒径的标准偏差）为40％以下，ζ电位范围为通过激光多普勒法在pH6.4下使用电泳测量-30至-60mV。钛酸钡粉末在900〜1200℃的温度下进行预烧结。钛酸钡粉末在制浆时具有优异的分散特性，能够部分抑制烧结后的钛酸钡的凝集。因此，它适用于多层陶瓷电容器介质层的材料。特别是钛酸钡的烧结密度为理论密度的95％以上，介电常数为4000以上。

摘要： A process for the production of ultrafine powders that includes subjecting a mixture of precursor metal compound and a non-reactant diluent phase to mechanical milling whereby the process of mechanical activation reduces the microstructure of the mixture to the form of nano-sized grains of the metal compound uniformly dispersed in the diluent phase. The process also includes heat treating the mixture of nano-sized grains of the metal compound uniformly dispersed in the diluent phase to convert the nano-sized grains of the metal compound into a metal oxide phase. The process further includes removing the diluent phase such that the nano-sized grains of the metal oxide phase are left behind in the form of an ultrafine powder.
