Novel Reagents for Chemical Vapor Deposition of Intermetallic Alloys

Abstract

Reactions of Hf(CH2SiMe3)4 with AlMe3 proceeded by formation of covalently bonded heterobimetallic intermediates with no alkyl exchange. Reaction with A1H3.NMe3 yielded A1(Ch2SiMe3)3. NMe3 and 'Hf(CH2SiMe3)H3'. Carbon blocks coated with this mixture produced a HfAlC2 coating which was effective in protecting the substrate from air oxidation at high temperatures.
