Bond compression bulk modulus and Poisson’s ratio of the polycomponent silicate glasses

摘要: Abstract The theoretical bulk modulus and Poisson’s ratio of the 65SiO 2 –15PbO–5CaO–(15− X )K O– Na O glass system ( =0–15 mol%) have been calculated using bond compression model. atomic ring size network has also obtained for each sample according to deformation These parameters interpreted quantitatively in terms most important structure factors. composition dependence these showed that elasticity hence response this is influenced by chemical nature modifying oxides. Moreover, variation estimated with K bc ) experimental e was studied obtain more information about glasses. results small values / are attributed very close (small-ringed) three-dimensional
