Hydrothermal crystallization of some II–VI compounds

Hydrothermal and Supercritical Water Processing of Inorganic Substances

“…ZnS can be grown in electronic-grade quality in supercritical water [49]. ZnSe, ZnTe, CdSe, and CdTe form stable solid phases in OH À solutions under hydrothermal conditions of T ¼ 350 C and grow on seeds in small thermal gradients, while under similar conditions, HgS decomposes, forming Hg, and PbS and CdS hydrolyze [50].…”

HgS: a rugged, stable semiconductor radiation detector material

“…12,13,14,15,16,17 The HgS phase diagram 18 shows a solid-solid phase transition, therefore HgS cannot be grown from the melt, and alternative methods are needed. At this time, we have begun to investigate hydrothermal growth, flux solution growth, and physical vapor transport.…”

Synthetic Strategies

“…Some II-VI compounds, such as ZnSe, ZnTe, CdSe, and CdTe, have also been recrystallized into large single crystals using the technique (Kolb, 1968), as well as aluminum orthophosphate, AlPO 4 (Kolb, 1980).
