Synthesis of indium phosphide for production of e.g. optoelectronic instruments comprises use of direct process from indium and phosphorus in completely closed reaction system

摘要

Indium phosphide is synthesized from indium and phosphors by a direct process in a completely closed reaction system using a reactor in which at least two containers are used one inside the other. Indium phosphide is synthesized from indium and phosphors by a direct process in a completely closed reaction system sing a reactor in which at least two containers are used one inside the other. The temperature and the pressure is brought to a maximum value of 1070-1250 (preferably 1100-1200) deg C and 1850-2000 bars respectively with a constant temperature increase w.r.t time according to the formula y = kx, where y is the temperature in deg C, x is the time in minutes and k is a constant with a vale of 5-20 deg C/minute.
