Abstract
A new method is described for studying reproducibly, the
kinetics of crystallization of calcium fluoride under conditions of
constant solution composition. The method can be used even at
very low supersaturation. The rate is proportional to the square of
the supersaturation, over the range of relative supersaturation,
S = 0.20 - 1.66. The results point to a surface controlled crystallization.
The rate is markedly influenced by the presence of phosphate.
