摘要

A new synthetic chalcoalumita in fine particles, Process for preparing the sameAnd a Thermal insulation and a pelu00edculaagricultural Agent containing the Synthetic chalcoalumita in fine particles.The above mentioned Objects are obtained by a chalcoalumita sintu00e9ticarepresentada by the following formula: (M1 (2 +) - X (m (X)) + (XAL) 4 (OH) B ((n + c)) where M1 mH2O represents (2 +) Zn (2 +) or Cu (2 +)M2 (2 +) is at least one selected from the group formed ionmetu00e1lico divalent porni (2 +), CO (2 +), Cu (2 +), Zn (2 +) and mg (2 +); a is 0.3 2,0 (with the condition that M1 and m2 are not equal) X is less than X / B is equal to 1.0 B 10; 14; (n) is at least one ion selected from the group consisting of SO4 (2 -) (HPO4 2 (CO3) 2 - SO3 (2), HPO3 (2 -), NO3 -)H2PO4 ion, CL, oh and a silicate; C 2 C 0.4,And M is 0 - 0; 4; Compound which has an average particle diameter of not more than approximately 3 Secondary micronesy a Bet specific surface area no greater than approximately 30 m2 / g,Compositions containing such chalcoalumita Synthetic Resin; and a pelu00edculaagricultural such Resin compositions.
