Abstract: Apparatus to form silicon carbide filaments which are essentially uniform throughout their cross-section, which includes a reaction chamber, a thermal screen surrounding the reaction chamber to equalize the temperature therein, a thermal gradient oven concentric with the thermal screen and surrounding the chamber, and a plurality of thermocouples located in the chamber and sensing temperature, and controlling the oven to provide for essentially uniform temperature distribution within the oven, the chamber having inlet means for the admission of organosilane so that conversion of heated tungsten to tungsten carbide is carried out essentially at uniform temperatures throughout the entire chamber; an electrolytic cell follows the chamber in the path of the filament.
