<P>PROBLEM TO BE SOLVED: To provide a porous molding excellent in crack resistance when a temperature is changed repeatedly from a high temperature to a low temperature. <P>SOLUTION: The porous molding excellent in crack resistance contains silicoaluminophosphate (SAPO), for example, SAPO-34 and/or aluminophosphate (ALPO) having a positive coefficient of linear expansion, and ALPO, for example, AIPO-D having a negative coefficient of linear expansion. A weight ratio (X)/(Y) between the weight (X) of SAPO and/or ALPO having a positive coefficient of linear expansion and the weight (Y) of ALPO having a negative coefficient of linear expansion is in the range of 0.125-9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
