Abstract
PURPOSE: To produce GaP with a little reducing gas in a short time by compression- molding GaPO4 power followed by reduction in a reducing atmosphere.
CONSTITUTION: Reaction container 52 is put into vertical type furnace 51. In container 52 disklike compression moldings 53 of GaPO4 powder are arranged on gas permeable boat 54. A reducing gas such as H2 gas is introduced from gas pass 56 to fill container 52 with a H2 gas atmosphere. Exhaust gas is exhausted from exhaust gas pass 55. GaPO4 moldings 53 are heated to an appropriate temp. with heater 57 set by the side of container 52, and they are reduced with H2 gas. Since the arrangement of moldings 53 accords with the flow of H2 gas, a H2 current of one direction is only required, and reaction products such as H2O are quickly exhausted. Because of moldings much starting material GaPO4 can be supplied as compared to powder, so the time required to obtain a fixed amt. of GaP is shortened in spite of slow proceeding of reduction, and the amt. of H2 gas used is reduced.
