Abstract

The preparation and pyrolysis of a blended precursor possessing Ti-N and Al-N bonds were investigated. The precursor was prepared by mixing (HAlNiPr), whose main component was a cage-type compound, and an aminolysis product of Ti(NMe2)4 with MeHNCH2CH2NHMe with a molar ratio of Ti:Al=2:1. IR analysis of the products pyrolyzed under NH3-N2 indicated that a large proportion of the organic groups in the precursor were removed by an amine-exchange reaction during the pyrolysis under NH3; thus, the products contained only a small amount of carbon. On the contrary, a considerable amount of carbon was present in the product pyrolyzed under Ar. Composites consisting of AlN and an NaCl-type compound were obtained after pyrolysis of the precursor under both NH3-N2 and Ar. The composition of the NaCl-type compound depended significantly on the pyrolysis atmosphere.
