Japanese Patent JP2821662
Kind Code:
B2
Abstract:
PURPOSE:To industrially produce a fine-grain titanium-base powder excellent in flowability. CONSTITUTION:This granular titanium-base powder is obtained by the hydrogenation-dehydrogenation processing and has 5-74mum particle diameters, and the average particle diameter is controlled to <=20mum and the flowability to <100sec/50g. The hydrogenated titanium-base lump is mechanically crushed and then classified to prepare the hydrogenated titanium-base powder having 5-74mum particle diameters and <=20mum average particle diameter, the powder is dehydrogenated at 500-58 deg.C in vacuum, and the dehydrogenated titanium-base lamp is crushed and disintegrated into the titanium-base powder.
