X-Ray diffraction patterns shows a good crystallinity of the composite with very sharp and neat peaks. TEM photographs shows the good distribution of the particles which have an average particle size of (3-6 nm). The microhardness is increased with the increasing of sintering temperatures having the height value at 15% chromia while the fracture strength behaves as a bell shape having again the height value at 15% chromia.}, keywords = {nanocomposite,sol,gel,Microhardness,fracture strength,TEM}, url = {https://etj.uotechnology.edu.iq/article_82098.html}, eprint = {https://etj.uotechnology.edu.iq/article_82098_946038087fdbd3c65fc24377907efd6d.pdf} }
