N2 - The addition of straight chain polyamines such as triethylenetetramine, tetraethylenepentamine, pentaethylenehexamine and 1,4-diaminobutane in the course of carbonation of basic calcium carbonate promoted the formation of disk-like vaterite of 1-1.5 μm in diameter and 0.1-0.2 μm in thickness. On the other hand, cyclic polyamines such as piperazine, 1-(2-aminoethyl) piperazine and 1,4-diazabicyclo [2, 2, 2] octane, and branching polyamine such as 2,2-dimethylpropylene, promoted the formation of spindle-like calcite. Only polyamine in which N-N distance is 0.3 nm or its integral multiple, promoted formation of the disk-like calcium carbonate. Hexagonal of basic calcium carbonate once dissolved in aquarious media and the disk-like calcium carbonate formed.
