tatement of the Problem: The special properties of ceramic materials are becoming increasingly important for many
applications in electrical, chemical and mechanical engineering. Oxide ceramic materials are used in a wide range of
industries, including mining, aerospace, electronics, medicine, etc. These materials show a high strength and hardness, as
well as a thermal, cracking, and corrosion resistance. Ceramics are considered as popular engineering materials due to their
excellent mechanical properties: good fracture toughness, high strength, elastic modulus, and wear resistance, used in many
engineering applications such as engine elements, valves, cutting tools, and moulds. In recent years, YSZ with its superior
combination of mechanical properties and chemical inertness has been employed in the biomedical field as an implant material.
The main aim of the present study is to investigate how the yttrium (III) oxide can influence the formation of monoclinic
zirconia crystalline phase in ceramics. The ceramic systems in the xY

were synthetized by sintering method in alumina crucibles at 14000C for two hours. For this work, we compared the samples
obtained in our laboratory with those used in the medical market, called sample M, T and C. For all samples were characterized
by investigations of XRD, and XAS analysis. The EXAFS analysis of absorption coefficient was processed by computer codes
CDXAS, XAS and IFEFFIT.
