INCREASED DENSITY PARTICLE MOLDING

摘要

A free-flowing metallurgical powder comprises particles of metal and/or metal oxide having unagglomerated number average particle diameters of between 2 and 250 µm and a coating on the particles of an at least partially hydrolysed hydrolysable compound, the coating comprising from 0.05% to 5% by weight of the particle. A sintering process comprises providing the free-flowing powder composition into a mold, at least 99% by weight of the composition consisting of particles of metal and/or metal oxide and heating and pressing the composition to sinter the powder.
