Paper Title:
Solution-Based Synthesis of Ultra-Fine ZrB2 Powders and ZrB2-SiC Composite Powders
  Abstract

Ultra-fine ZrB2 powders and ZrB2-SiC composite powders were synthesized by solution-based method, using zirconium oxynitrate (ZrO(NO3)2•2H2O), boric acid (H3BO3), phenolic resin, and tetraethyl orthosilicate (TEOS) as raw materials, respectively. The zirconia sol with other precursor was formed via adjustment of the pH value. After drying, grinding and sieving, the precursor powders were obtained. Exposed to carbothermal reduction heat treatments (1300°C~1500°C, 0.5h, flowing argon), pure ZrB2 powders and ZrB2-SiC composite powders with fine particle size (~1μm) were synthesized.
