(57) [Summary] [Purpose] To efficiently manufacture low-temperature sinterable ceramics without the need for a crushing and refining step of glass and a subsequent mixing step for a long time. A low-temperature sinterable ceramic that has excellent properties such as strength and a low dielectric constant can be manufactured. [Structure] When a low temperature sinterable ceramics is manufactured by coating an inorganic filler with gel glass obtained by a sol-gel method and molding and firing the obtained composite powder, alumina powder is added in the step of manufacturing gel glass. In addition to the addition, an inorganic powder other than alumina is used as the inorganic filler. [Effect] In the temperature rising process of firing of the molded body obtained from the gel glass-inorganic filler composite powder, first, when the softening point of the glass is exceeded, sintering starts, and when the maximum temperature of firing is reached, the sintering is almost completed. finish. Subsequently, the reaction of the alumina particles added to the gel glass proceeds while maintaining the maximum temperature, and anorthite precipitates. |
