Abstract

Temporal stability of amorphous calcium carbonate (ACC) has been affected in a deliberate manner in purely abiotic systems. The authors monitored the progress of calcium carbonate pptn. at high pH from solns. contg. different amts. of sodium silicate. Growing ACC particles provoked spontaneous polymn. of silica in their vicinity, which was probably caused by a local decrease of pH nearby the ...
