Nuclei, site ingestion

Three main constraints tend to decrease the rate of product formation through nucleus growth. These are coalesence of nuclei, ingestion of sites potentially capable of generating nuclei, and crystal boundaries, and are explained below. 

Two factors are identified as limiting nucleus development, by preventing imrestricted expansion, and thereby curtailing the acceleratory process. These are the coalescence of nuclei and the ingestion of potential nucleus forming sites. 

During reaction, the number of potential nucleus-forming sites decreases from the initial value A(, at i = 0, to N (t) at time t, because N t) sites have been activated to form nuclei and T/jCO site been eliminated by ingestion, so that ...
