Single-source-precursor synthesis and air-plasma ablation behavior of (Ti,Zr,Hf)C/SiC ceramic nanocomposites at 2200 °C

Abstract

were prepared upon pyrolysis of novel (Ti,Zr,Hf)-containing single-source-precursors (SSPs), followed by spark plasma sintering. A thorough characterization was conducted to elucidate the synthesis of the SSPs, polymer-to-ceramic transformation, chemical/phase compositions and microstructure of the SiTiZrHfC-based ceramics. The results revealed the feasibility of synthesizing the nanocomposites with high (Ti,Zr,Hf)C content using SSP method. These nanocomposites were
