Abstract

PURPOSE: To produce powder of a compound AB of high purity, uniform particle sizes and constant crystal shape by injecting a gas contg. an element B in a molecular state into the vapor of an element A or into an atmosphere contg. the element A of molecular state filled in the high temp. zone of a vapor phase reaction chamber.
CONSTITUTION: The term "compound AB" signifies II-VI group compound semiconductors, for example, ZnS, ZnSe, etc., III-V group compounds, for example, GaAs, GaP, etc., or their carbide, nitride, etc. Next, in producing the powder of compound AB (e.g.; ZnSe powder), first the inside of a vapor phase reaction chamber 1 is evacuated, after which vapor of A (Zn) or a gas 6 contg. A in the molecular state is introduced P1 into a high temp. part 2, and is maintained in the gaseous atmosphere 6 of a high concn. Next, a gas 7 contg. B (Se) as molecule is introduced P2 into this atmosphere, and the vapor phase reaction of the A and the B is effected whereby fine powder particles 8 of the compound AB are formed and captured in a low temp. zone 3. An inert gas such as Ar is included together with he gas as a carrier gas into the gases to be introduced P1, P2.
