摘要： Process for the preparation of a ceramic nanowire preform, in particular, a process for the preparation of a ceramic nanowire preform by combining a template technique and a preceramic polymer conversion technique. The process uses carbonaceous material as a template, and prepares an isotropic ceramic nanowire preform by controlling the ratio of a precursor to a solvent, the amount of a catalyst and the ratio of a prepared precursor solution to the carbonaceous template, wherein the preform is isotropic and has lower bulk density and higher volume fraction.
