Our computational studies for the physical vapor transport crystal growth of Hg2Cl2-Cl2 system evidence suggests that the PVT growth process exhibits the diffusion-dominated behaviors for aspect ratios more than and equal to 10, which would provide purely diffusive transport conditions adequate to microgravity environments less than 10−3g0. Also, the regimes of high temperature difference based on the fixed source temperature of 380
oC, where ΔT is relatively large enough for the crystal growth of mercurous chloride, the transport rates do not keep increasing with ΔT but tend to some
constant value of 2.12 mole cm−2s−1. For the aspect ratios of 5, 10, and 20, the transport rate is directly proportional to the total pressure of the system under consideration. For Ar = 5, the rate is increased by a factor of 2.3 with increasing the total pressure from 403 Torr to 935 Torr, i.e., by a factor of 2.3. For both Ar = 10 and 20, the rate is increased by a factor of 1.25 with increasing the total pressure from 403 Torr to 935 Torr.
