Abstract

PURPOSE: To efficiently manufacture high purity gallium oxide in large quantities by preoxidizing a mixture of metallic gallium with gallium ozide and oxidizing it at a high temp.
CONSTITUTION: Metallic gallium is melted by heating to the m.p. or above, that is, ≥29.7°C, gallium oxide is added to the molten gallium in 1.5:1 weight ratio, and they are mixed to form a thin metallic gallium layer on the surface of the gallium oxide. This mixture is heated to 500W700°C in an atomosphere contg. oxygen or slurrified with water and heated to 29.7W100°C in an atmosphere contg. oxygen. About 90% of the thin metallic gallium layer is oxidized. The resulting gray powder is heated to 700W1,200°C in an atmosphere contg. oxygen to oxidize the remaining metallic gallium. In this stage heat of reaction is generated by a smaller quantity because of a smaller part to be oxidized, and high purity gallium oxide is efficiently obtd. in large quantities without causing sintering.
