In this study nanocomposite of Al2O3-ZrO2 was produced by Mechanicaly Activated Self propagating High-temperature Synthesis (MASHS) using aluminium powder and industerial zirconia as inexpensive starting materials. To find the specifications of the products X-ray diffraction (XRD) and scanning electron microscopy(SEM) were used. The initial mixture with the ratio of Stoichiometry was milled for 1,3,6 and 9 hours. After 1hour of milling,sampels were capable of Synthesising in furnace at oxygen atmosphere. By Measuring the grains of synthesised phases showed that average size of the grains of product were 25 nm. By increasing milling time to 3 hours, the peaks of tetragonal zirconia in synthesised sampel were intensified more. By continuing the milling to 6 hours the phase of cubic zirconia was observed in synthesised sampels. and by 9 hours milling before synthesis ,phase changes and change in the composition in milling product was observed.
