The present study mainly aims to focus of the structural properties of some coppermolybdate glass-nanocomposites by studying the X ray diffraction (XRD), transmission electron micrographs (TEM) and differential scanning calorimetric (DSC) analysis and mechanical property like microhardness of them has been evaluated from Vickers hardness (HV ) tester. XRD and TEM studies reveal the size and distribution of CuMoO4 nanoparticles which have been confirmed from Americal society for testing materials (ASTM) data sheet. From the DSC analysis, glass transition temperature (Tg ) and crystallization temperature (Tc ) have been evaluated and correlated with their structures. Vicker-indentation method has been employed for the measurement of microhardness of samples under investigation. A structural model of cuppermolybdate glass-nanocomposite system has been developed to correlate between strucral and mechanical properties of them.
