摘要:
The present invention relates to a process for the production of non-swellable phyllosilicate tactoids, comprising A) producing a synthetic smectite of the formula I in a high-temperature-melt synthesis [Mn/Valenz]inter[MImMIIo]oct [MIII4]tet X10Y2 (I) B) if the interlayer cation M does not already have a hydration enthalpy from −6282 to −406 [kJ/mol], exchanging the interlayer cation M with a cation having a hydration enthalpy from −6282 to −406 [kJ/mol] by a cation-exchange method, C) dispersing phyllosilicate in an aqueous system, and D) exchanging M with a cation having a hydration enthalpy from −405 to 0 [kJ/mol], by a cation-exchange method.
