MANUFACTURING METHOD OF SEMICONDUCTING CERAMIC SINTERED BODY WITH PEROVSKITE STRUCTURE
According to the present invention of a method of manufacturing a ceramic sintered body, the method comprises the steps of: (S10) mixing raw material powder containing at least two compounds selected from calcium carbonate (CaCO3), zirconium oxide (ZrO2), titanium oxide (TiO2), and manganese dioxide (MnO2); (S20) calcinating the mixed raw material powder; and (S30) sintering a calcinated body of the calcinated raw material powder, thereby obtaining the ceramic sintered body having an ABO3 perovskite structure and excellent resistivity at a room temperature.
본 발명의 세라믹 소결체의 제조방법에 의하면, 탄산칼슘(CaCO), 산화지르코늄(ZrO), 산화티타늄(TiO) 및 이산화망간(MnO) 중에서 선택되는 2개 이상을 포함하는 원료 분말을 혼합하는 단계(S10)와, 상기 혼합된 원료 분말을 하소(calcination)하는 단계(S20)와, 상기 하소된 원료 분말의 하소체를 소결하는 단계(S30)를 포함하고 ABO의 페로브스카이트 구조를 갖고, 상온 비저항 특성이 우수한 세라믹 소결체를 얻을 수 있었다.
