A novel, low cost method for fabrication of oxide fibers and first results for yttrium aluminum garnet (YAG) and mullite fibers grown by this method are presented in this paper. Starting with either commercially available powders, or nano-sized powders a variety of experimental conditions for extrusion of fibers and subsequent heat treatments were investigated. A four lamp, Quadrupole Furnace was especially designed and built with which the microstructure could be tailored as a function of temperature and furnace traverse rate. Fibers with diameters of 30 μm can be produced using this method.
