Abstract

Novel AlN precursors have been prepared by reactions in a LiAlH₄-CH₃NH₂·HCl-(CH₃) ₂NH·HCl system with several nominal CH₃NH₂·HCl:(CH₃) ₂NH·HCl (M:D) ratios (M:D=4:1, 6:1 and 8:1). Considerable amounts of precursors were soluble in both tetrahydrofuran and benzene. Soluble precursors consist of polymeric/oligomeric species possessing both [H₂AlNMe₂] and [HAlNMe] units, and ring-type (H₂AlNMe₂)₃ was also present only if M:D=4:1. The precursors were converted into single-phase AIN with relatively high ceramic yields (up to 58 %) by pyrolysis at 1600°C under Ar.
