A manufacturing method of highly crystalline Barium-Titanate and highly crystalline Barium-Titanate powder manufactured by the same

摘要

The present invention relates to a highly crystalline barium titanate powder prepared by the method of the highly crystalline barium titanate prepared and the method, the manufacturing method of the highly crystalline barium titanate according to the present invention is allowed to warm to the barium (Ba) a barium hydroxide raw materials ionize step to prepare; Steps of: preparing a titanium (Ti) raw materials dispersed in an acid or a base; To obtain a mixture, and reacting barium seed (seed) for the barium hydroxide and titanium raw materials; The mixture of barium titanate and a pure seed and grain growth inhibitor to the step of grain growth; includes. Since this a highly crystalline barium titanate powder produced in a highly crystalline production method of barium titanate and a method according to the invention is a mixture of barium hydroxide and titanium raw material prepared by slow grain growth under generate rapid nucleation and high temperature, high pressure, fine particles being a high crystal axis ratio (c / a) to have, between the particle size distribution is not excellent, hardly exist pores in the interior, there is no large particle, necking (necking) particles when the not dispersibility is very good and, due to high surface density plastic this phenomenon has an effect not aggregation is sintered stably in a wide area. ;
