Resumen:
A new route to prepare zirconium carbide preceramic powders has been developed using alkoxides polymerized with polyalcohols. Preceramics were pyrolized under vacuum to form metal carbides/metal oxide materials . Best carbide yelds were obtained using very low heating rates (0.5ºC/min) and reaction time at final temperature higher than 30 min. An explanation of the possible parameters that govern zirconium carbide formation is presented.
