Title: Production of gallium phosphate and sintered material
Inventor: ITO EIJI
IPC: C01B25/37
Filed: 1988-02-23
Abstract: PURPOSE:To obtain high-purity gallium phosphate by a simple method by heating gallium phosphide at a specific temperature in an oxidizing atmosphere. CONSTITUTION:Gallium phosphide is heated in an oxidizing atmosphere at 1,100-1,350 deg.C to give gallium phosphate. Gallium phosphate powder thus obtained is sometime used as powder as it is and often used a sintered material for sputtering target plate, etc. In the operation, the powder is simply mixed with a very small amount of pure water, press molded, heated to 1,000-1,300 deg.C and sintered so that a sintered material can be prepared but mutual bond strength between the powder is weak and when the surface of the sintered material is strengthened, the powder is readily released. In order to improve the drawback, when an aqueous solution of phosphoric acid is used instead of pure water and sintering is carried out at 1,000-1,300 deg.C, phosphoric acid plays a role of a binder so that mutual bonding strength between powdery can be increased.
