Abstract:
1. A method for forming a powder containing a metal or metal derivative comprising: providing a medium; dispersing a vapor or liquid into the medium, the vapor or liquid containing an organometallic compound; and heating the medium to a temperature at or above the thermal decomposition temperature of the organometallic compound, wherein the organometallic compound has the formula (R 1 ) m M(PR 2 3 ) x , where M is a metal selected from a Group VIIb, VIII, IX or X metal wherein (a) when M is manganese, technetium or rhenium, m is 1, x is 5 and m+x is 6; (b) when M is iron, ruthenium or osmium, m is 0, 1, 2, 3 or 4; x is 2, 3, 4 or 5 and m+x is 4, 5, 6 or 7; (c) when M is cobalt, rhodium or iridium, m is 1, 2, 3 or 4 and x is 2, 3 or 4 and m+x is 4, 5, 6, 7 or 8; and (d) when M is nickel, palladium or platinum, m is 0 or 2, x is 2, 3 or 4 and m+x is 2, 3, 4, 5 or 6; each R 1 is independently selected from the group consisting of hydrogen, deuterium, N 2 , H 2 , D 2 and a group of the formula —CR 3 2 —CR 3 2 —R 4 ; each R 2 is independently selected from the group consisting of lower alkyl, aryl, arylalkyl, alkoxy, aryloxy, arylalkoxy, alkylsilyl, arylsilyl, arylalkylsilyl, alkoxysilyl, aryloxysilyl, arylalkoxysilyl, alkylsiloxy, arylsiloxy, arylalkylsiloxy, alkoxysiloxy, aryloxysiloxy, arylalkoxysiloxy, alkylsilylalkyl, arylsilylalkyl, arylalkysilylalkyl, alkoxysilylalkyl, aryloxysilylalkyl, arylalkoxysilylalkyl, alkylsiloxyalkyl, arylsiloxyalkyl, arylalkylsiloxyalkyl, alkoxysiloxyalkyl, aryloxysiloxyalkyl, arylalkoxysiloxyalkyl, alkylsilylalkoxy, arylsilylalkoxy, arylalkylsilylalkoxy, alkoxysilylalkoxy, aryloxysilylalkoxy arylalkyloxysilylalkoxy, alkylsiloxyalkoxy, arylsiloxyalkoxy, arylalkylsiloxyalkoxy, alkoxysiloxyalkoxy, aryloxysiloxyalkoxy, and arylalkoxysiloxyalkoxy; each R 3 is independently selected from the group consisting of hydrogen, deuterium, C 1 -C 6 alkyl, C 1 -C 6 cycloalkyl, phenyl, benzyl, (C 1 -C 2 alkyl or alkoxy) 3 -silyl, and (C 1 -C 2 alkyl or alkoxy)3-siloxy and wherein at least two groups R 3 are selected from the group consisting of hydrogen and deuterium, R 4 is hydrogen or deuterium; and wherein when M is cobalt and one group R 1 is selected to be N 2 , then m is 2 and the second group R 1 is hydrogen or deuterium.
