Abstract: In the present work the tellurite glass a function of alkali metals as network intermediate with composition 85TeO2 / 5Nb2O5 / 5ZnO/ 5Li2O in mol% were been prepared. These glasses contain Li2O can be promising used in optical devices because it has advantage optical properties compared with other tellurite glasses. The physical parameters of these glass studied with respect to values of density, , molar volume, Vm, linear refractive indices, n0 , nonlinear refractive index, n2 , electronic polarizability, m, molar refraction, Rm, metallization criterion, M (n0 ), and third order non-linear optical susceptibility, (3),. The Sellmeier gap energy, Es , and dispersion energy, Ed , were calculated besides the theoretical third order of nonlinear optical susceptibility, (3), calculated by used Lines model. Measure the thermal stability and the glass transition temperature by differential thermal analysis (Shimadzu DTA 50) which can be determine the glass transition temperature, Tg , onset crystallization temperature, Tc , and melting temperature, Tm. These glass have values as; = 5.231 gmcm-3 , Vm= 28.75 cm-3 , n0= 2.2228 at 435.84 nm, m= 6.478Å3 and Rm=16.024 mol-1 cm3 at 435.84nm. and Es = 6.54 eV, Ed= 20.65 eV.
