Abstract:
1. A method of forming a ceramic composite, the method comprising: mixing a pre-ceramic polymer and a solvent into a powder of an ultra-high-temperature ceramic (UHTC) material, and allowing the pre-ceramic polymer to coat grains of the UHTC material approximately uniformly, wherein the process of mixing comprises: wherein said UHTC material is a boron-containing material, comprising at least one of HfB 2 and ZrB 2 and having a melting temperature of at least 2000° C.; thermally consolidating the mixture at a consolidation temperature of at least about 2000° C. for a thermal consolidation time interval in a range of about 30-180 minutes and at an applied pressure of at least 10 MPa; and allowing acicular reinforcement rods or fibers or whiskers to grow from the UHTC grains during thermal consolidation.
