Zirconia fibers have been prepared by convertional method using cotton threads
impregrated in zirconium oxychloride solution ( ZrOCl2. 8H2O ). X-ray
diffraction shows the crystallinity of zirconia and optical microscopy shows the
fibers fabrication. Differnet percentage ( 2 ,4 ,8 , 10 and 12 ) of prepared zirconia
fibers mixed with ZnO powder.
All the specmen sintered at 1250 °C for 2hrs. Physical properties (density and
volume shrinkage) were measured and Mechanicl properties (Vicker ̉s
hardness,fracture strength and fracture toughness by indentation method ) were
calculated, 10% of fiber content has the maximum values for these properties for
the composite.
