摘要: Oxyfluoride glass system based on 30ZnF2-20TeO2-(50 − x)B2O3−xSm2O3, (where x = 0, 0.5, 1.0, 1.5, 2.0, 2.5 mol %) were prepared. The density of each was measured and the molar volume calculated. model developed by Makishima Mackenzie (M-M) gave reasonable estimation for different constants elasticity (Young’s modulus, bulk shear Poisson’s ratio). Vickers indentation tests performed series samples. These connections used to relate conventional Hardness. Fracture toughness, dissociation energy packing also investigated. relationship between machinability brittleness materials studied. Exposition M-M proved be good oxyfluoride glasses.
