Description

ABSTRACT:
Coatings of metals, metal alloys, metal carbides, nitrides, borides, silicides and phosphides are provided. A precursor having organic ligands bonded to one or more metal atoms, such precursor having the element X also bonded directly or indirectly to the metal or metals, is pyrolyzed on a substrate surface to give a coating of M.sub.a X.sub.b. M represents a transition, lanthanide or actinide metal or tin, X represents C, N, B, Si, or P, and a and b represent the atomic proportions of M and X. The subscript b may be zero if an alloy or pure metal is to be prepared. The product M.sub.a X.sub.b can be prepared by relatively low temperature pyrolysis and the precursor can be used as a solution or a low melting solid.
