摘要

1 to 100 parts by mass of a hydrogen carbonate compound (A) represented by AHCO ₃ (wherein A is Na or K) and B _n X ( _wherein B is Na or K and X is CO ₃ , SO ₄ , and SiO _3, F, Cl, or Br, n is 1 or the compound represented by an integer of 2), which is determined by the valence of X (B) 0 parts by weight of ~99 parts by weight (where (a) and (B) , And a step of heating the molded body to a temperature in the range of 100 ° C to 500 ° C and a water vapor in the range of 1.0 g / m ^{3 to} 750000 g / m ³ (A) in an atmosphere containing at least 90% by mass of the hydrogenated compound (A), thereby obtaining a porous formed article.
