| 内容： | To provide a perovskite type ceramic obtained by a combustion synthesis and having superior sintered body characteristics, and its manufacturing method. ! The perovskite type ceramic is a ceramic having a perovskite type crystal structure, and obtained by blending reaction raw materials containing at least a metal powder containing a group 4 element having a specific surface of 0.01-2 m2/g, carbonate of elements including a group 2 element and sodium perchlorate at prescribed ratios respectively and subjecting them to the combustion synthesis at an adiabatic flame temperature of 1,500°C or higher. The above-mentioned group 4 element is titanium and the above-mentioned group 2 element is at least one element selected from among strontium, barium and calcium. ! (C)2007,JPO&INPIT |
