Preparation of Precursors for Aluminum Nitride-Based Ceramic Composites from Cage-Type and Cyclic Building Blocks

Abstract:

Article Preview

Precursors for nitride-based ceramic composites have been prepared from two types of building blocks, cage-type poly(iminoalane) with Al-N backbones and cyclic poly(silazane) with Si-N backbones. Two combinations of poly(iminoalane) and cyclic poly(silazane) were utilized to prepare precursors. For the combination of poly(isopropyliminoalane) and [MeSi(H)NH]n, two building blocks were connected via dehydrocoupling, while Pt-catalyzed hydrosilylation was utilized for the combination of poly(allyliminoalane-co-ethyliminoalane) and [Me(H)SiNH]n. The ceramic yields of poly(iminoalane)s increased upon reactions with [MeSi(H)NH]n.
