Solid transport rate in the vapor-solvent growth system ZnS:I

Abstract

Measurements of the rate of solid transport have been carried out in the system ZnS:I with two different sealed-tube geometries. The cubic ZnS crystals obtained are comparable in size and quality to those grown from HC1. With increasing pressure, the transport mechanism is at first diffusion-then convection controlled. In the range of diffusive flow, the pertinent theory for multireaction multi-component systems is in satisfactory agreement with the experimental data. © 1964.
