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 yields were obtained using very low heating rates (0.5°C/min) and reaction time at final temperature higher than 30 min. An explanation of the possible parameters that govern zirconium carbide formation is presented. Information provided by the agent in SIGEVAKey Words
