Abstract: In this paper zirconia ceramic fibers are prepared via extrusion. The influence on fibers density and shrinkage by PVA and glycerin content is studied via parameter-transformation procession. Furthermore, the precursor of zirconia fibers are,analysed by TG and DTA, and scanning electron microscopy is performed, too. In the experiment binder Is substituted by sol, which improves density of fibers.
