摘要:
A method for producing a ceramic scintillator comprising the steps of mixing a rare earth compound with sulfuric acid and/or sulfate to cause their reaction to obtain a product; calcining the product to obtain calcined powder; reducing the calcined powder to obtain rare earth oxysulfide powder; molding the rare earth oxysulfide powder to obtain a green body; and sintering the green body; a pulverization step being conducted to adjust the particle sizes of the product and/or the calcined powder at least before the reduction step. Translation of the Abstract as published by WIPO This method for producing a ceramic scintillator includes: a mixing step for obtaining a product by mixing and reacting a rare earth compound and sulfuric acid and/or a sulfate; a calcining step for obtaining a calcined powder by calcining the product; a reduction step for obtaining a rare-earth oxysulfide powder by reducing the calcined powder; a molding step for obtaining a molded article by molding the rare-earth oxysulfide powder; and a sintering step for sintering the molded article. Furthermore, the method for producing a ceramic scintillator is characterized by including a pulverization step for adjusting the particle diameter of the product and/or the calcined powder prior to at least the reduction step.
摘要:
Provided is a honeycomb structure having low heat capacity and high thermal diffusivity, and that follows the ambient temperature change rapidly. A honeycomb structure 100 includes a pillar-shaped honeycomb structure body 4 having a porous partition wall 1. The honeycomb structure body 4 includes a plurality of cells 2 defined by the partition wall 1 so as to extend from a first end face 11 to a second end face 12 of the honeycomb structure body 4, the partition wall 1 is formed by a porous body including a silicon phase as a main phase and an oxide, and the oxide includes a first oxide made of an alkali earth metal oxide, Al 2 O 3 , and SiO 2 .
