Abstract
Prodn. of arsenides or phosphides of main Gp. III elements, esp. Ga, at below the sublimation point of As or red P, is carried out by grinding and tempering a stoichiometric mixt. of the elements forming the cpd. concerned. Polycrystalline almost stoichiometric AIIIBV semiconductor material can be produced economically in open, i.e. not sealed or evacuated, reactors, even in kg amts. Pref. grinding and tempering are carried out repeatedly (pref. 3-8 times) in consecutive separate stages. The first tempering is at 200-400 degrees C below the sublimation point and the subsequent tempering stages a little below the sublimation point. Each tempering stage lasts for 15-45 min and the prod. is ground down to an average particle size of at least 2 mum in the second and subsequent stages.
