MOLDED SINTERED BODY, AND METHOD FOR PRODUCING MOLDED SINTERED BODY
To provide a molded sintered body having high catalytic activity and high crushing strength, which comprises a mayenite-type compound and a transition metal supported on the mayenite-type compound, and to provide a method for producing the molded sintered body.SOLUTION: A method for producing a molded sintered body, which comprises (i) a step of preparing a mixture by mixing a precursor of a mayenite-type compound and a raw material for a sintered inorganic binder; (ii) a step of molding the mixture to prepare a molded body of the mixture; (iii) a step of sintering the molded body to produce a calcined product; and (iv) a step of supporting a transition metal on the calcined product to prepare a sintered molded product. In the step (i), the raw material for the sintered inorganic binder is blended in an amount that the content of sintered inorganic binder in the sintered molded product (iv) amounts 3 to 30 parts by mass per 100 parts by weight of the sintered molded product (iv).SELECTED DRAWING: Figure 1
【課題】マイエナイト型化合物およびマイエナイト型化合物に担持した遷移金属を含む、触媒活性が高く、かつ圧壊強度が高い成形焼結体、およびその成形焼結体の製造方法を提供する。【解決手段】本発明の成形焼結体の製造方法はマイエナイト型化合物の前駆体および無機バインダー焼結物の原料を混合して混合物を作製する工程、混合物を成形して混合物の成形体を作製する工程、成形体を焼成して焼成物を作製する工程、および焼成物に遷移金属を担持して成形焼結体を作製する工程を含み、混合物を作製する工程は、無機バインダー焼結物の含有量が、成形焼結体１００質量部に対して３〜３０質量部になるように、無機バインダー焼結物の原料を配合する。【選択図】図１
