Method for producing conductive mayenite compound and sintered body of conductive mayenite compound

The present invention relates to a method for producing a conductive mayenite compound and a sintered body of a conductive mayenite compound. The present invention relates to a method for producing aconductive mayenite compound capable of obtaining a sintered body having a relatively flat surface. A manufacturing method is a method for producing a conductive mayenite compound, wherein the methodcomprises: (1) a step of preparing calcined powder which contains calcium oxide and aluminum oxide at a molar ratio of CaO:Al2O3 being 13:6-11:8 ; and (2) maintaining a treated body containing the calcined powder pressurized in a pressure range of 1-200 kg/cm2 in the reducing atmosphere of at least one of a Ti-containing member and a Ca source in a temperature range of 1220-1380 DEG C. 本发明涉及导电性钙铝石化合物的制造方法和导电性钙铝石化合物的烧结体。本发明涉及种能够得到具有较平坦的表面的烧结体的导电性钙铝石化合物的制造方法。种制造方法，其为导电性钙铝石化合物的制造方法，其中，所述方法具有：(1)准备煅烧粉的工序，所述煅烧粉以换算成CaO：AlO的摩尔比为13:6～11:8的比例含有氧化钙和氧化铝；和(2)将包含所述煅烧粉的被处理体在以1kg/cm～200kg/cm的范围的压力加压的状态下、并且在包含Ti构件和Ca源中的至少者的还原性气氛下、在122
