ABSTRACT

The influence of borate-boron on the crystal form of calcium carbonate has been studied experimentally. And it has been found that borate ions in a parent solution favor the formation of calcite. This experimental result is in good agreement with the prediction from the trend that chemical species which are more easily coprecipitated with calcite or aragonite favor the formation of aragonite or calcite respectively, because the authors reported previously that borate ions are more easily coprecipitated with aragonite than with calcite.
