    摘要: A method of making a hard constituent powder coated with at least one iron group metal, Me, by dissolving and complex binding at least one of Me.sub.n (NO.sub.3).sub.m and Me.sub.n (SO.sub.4).sub.m and other similar Me.sub.n --X.sub.m compounds containing X-groups with low or no carbon content, preferably Me-nitrates, solely or together with one or more metal salts of at least one iron group metal containing organic groups in at least one polar solvent with at least one complex former comprising functional groups in the form of OH or NR.sub.3, (R=H or alkyl). Hard constituent powder is added to the solution. The solvent is evaporated and remaining powder is heat treated in an inert and/or reducing atmosphere. As a result, coated hard constituent powder is obtained which after addition of a pressing agent can be compacted and sintered according to standard practice.

    摘要: A method wherein one or more metal salts of at least one iron group metal containing organic groups are dissolved and complex bound in at least one polar solvent with at least one complex former comprising functional groups in the form of OH or NR.sub.3, (RH.dbd.H or alkyl). Hard constituent powder and, optionally, a soluble carbon source are added to the solution. The solvent is evaporated and the remaining powder is heat treated in an inert and/or reducing atmosphere. As a result, coated hard constituent powder is obtained which after addition of a pressing agent can be compacted and sintered according to standard practice to a body containing hard constituents in a binder phase.

    摘要: A method for manufacturing anatase TiO2 nanoparticles comprises mixing (210) of Ti-containing alkoxide precursors with a solvent into a precursor solution, hydrolyzing (212) the precursor solution to yield a mixture of a fine titanium containing precipitate and the solvent and hydrothermally treating (214) the precipitate at an elevated temperature in a basic medium. The basic medium is provided after the hydrolysis. The basic medium comprises basic amines. A highly active photocatalytic material is thus presented, comprising anatase TiO2 nanoparticles, which have a mean diameter of less than 100 nm and have at least one of a {111}, a {112}, and a {100} crystal face. The material can be tuned for selective carboxylate-surface coordination.
