摘要：

SrMoO4 nanoplates were synthesized by a facile reverse microemulsion method at room temperature. Energy evolution of this in situ growth process was monitored by means of a microcalorimeter. A sharp exothermic peak for the initial reaction and two discontinuous relatively weak exothermic peaks for the subsequent crystal growth emerged on the microcalorimetric heat flow curve. Based on the in situ thermokinetic data, the rate constants of the nucleation process and crystallization process at 298.15 K were calculated to be 4.078×10-3 and 5.033×10-4 s-1, respectively. The growth mechanism and energy evolution were investigated.
