Abstract:

A process for the high pressure synthesis of Indium Phosphide using an independent temperature control of a three zone furnace incorporating a heat pipe provides a stable temperature profile throughout the synthesis cycle. Internalexternal pressure control of the quartz ampoule is maintained by use of a water cooled baffle and a temperaturepressure balancing program. Complete synthesis is achieved in less than five hours. Patents. mjm
