Study some physical and mechanical properties of ceramic-ceramic fibers composite

الملخص EN

Zirconium fibers have been prepared by conventional method using cotton threads impregnated in zirconium ox chloride solution ( ZrOCl2.

8H2O ).

X-ray diffraction shows the crystallinity of Zirconium and optical microscopy shows the fibers fabrication.

Different percentage (2, 4, 8, 10 and 12) of prepared Zirconium fibers mixed with ZnO powder.

All the specimens sintered at 1250 °C for 2hrs.

Physical properties (density and volume shrinkage) were measured and Mechanics 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.
