Abstract: PURPOSE:To obtain a high purity soln. of a V group or III-V group compound in a III group element as a solvent without causing a change in the composition of the III-V group soln. even by long-time heat treatment by purification by heat treatment in H2 wherein said solute is added in a larger amount than the necessary amount. CONSTITUTION:Indium as a solvent 1 and a larger amount of many pieces of InP 2 than the amount of InP required to saturate In at the heat treatment temp. are charged into the soln. holders of a boat 3 for heat treatment. At this time, InP floats on the In solvent because it has lower specific gravity than In. The boat 3 is put in a furnace where H2 flows, and heat treatment is carried out at the heat treatment temp. for the necessary time to remove impurities such as Si. With the passage of time, P is evaporated. Even if P is evaporated, InP is dissolved to compensate the evaporated P, and the composition of the resulting satd. soln. 5 can be maintained.
