The subject matter on appeal relates to a free-flowing
metallurgical powder comprising particles of metal and/or metal
oxide having a coating thereon of an at least partially
hydrolysed compound. Further details of this appealed subject
matter are set forth in claims 1 and 4, the sole claims on
appeal, which read as follows:
1. A free-flowing metallurgical powder comprising
particles of metal and/or metal oxide having unagglomerated
number average particle diameters of between 0.01 μm and 5 mm
and a coating on the particles consisting essentially of an at
least partially hydrolysed hydrolysable compound, the coating
comprising from 0.005% to 10% by weight of the particles.
4. A free-flowing metallurgical powder comprising
particles of metal and/or metal oxide having unagglomerated
number average particle diameters of between 0.01 μm and 5 mm
and a coating on the particles of an at least partially
hydrolysed hydrolysable Si compound, the coating comprising from
0.005% to 10% by weight of the particles, wherein the
hydrolysable compound comprises a material having the structural
formula of
