MOLDED SINTERED BODY, AND METHOD FOR PRODUCING MOLDED SINTERED BODY
Provided is a molded sintered body containing a mayenite-type compound, an inorganic binder sintered product, and a transition metal, wherein the content of the inorganic binder sintered product is 3-30 parts by mass with respect to 100 parts by mass of the molded sintered body, and in the pore diameter distribution of the molded sintered body obtained by measuring the pore diameter distribution by means of the nitrogen adsorption method, the molded sintered body has at least one pore peak in the pore diameter range of 2.5-20 nm and 20-350 nm, respectively. Also provided is a method for producing a molded sintered body, the method comprising: a step for mixing a precursor of a mayenite-type compound and a raw material of an inorganic binder sintered product and producing a mixture; a step for molding the mixture and producing a molded body of the mixture; a step for firing the molded body and producing a fired product; and a step for supporting a transition metal onto the fired product and producing a molded sintered body, wherein the step for producing a mixture includes mixing raw materials so as to satisfy said inorganic binder content, thereby obtaining a molded sintered body having high catalytic activity and high crush strength.
提供一种成型烧结体，成型烧结体含有钙铝石型化合物、无机粘合剂烧结物以及过渡金属，无机粘合剂烧结物的含量相对于成型烧结体100质量份为3～30质量份，在通过氮吸附法进行细孔径分布测定得到的成型烧结体的细孔径分布中，成型烧结体在细孔径2.5～20nm的范围内以及20～350nm的范围内分别具有至少一个细孔峰。还提供一种成型烧结体的制造方法，包括将钙铝石型化合物的前驱体以及无机粘合剂烧结物的原料进行混合来制备混合物的工序，将混合物进行成型来制备混合物的成型体的工序，将成型体进行烧成来制备烧成物的工序以及在烧成物上负载过渡金属来制备成型烧结体的工序；其中，制备混合物的工序中，对原料进行配比以满足上述无机粘合剂含量，通过该方法获得催化活性高、抗压强度高的成型烧结体。
