Abstract

A systematic characterization of optical, chemical and thermo-mechanical properties of R₂O-MO-TeO₂ glasses as function of alkali metals as network modifiers and network intermediate was performed. Properties such as thermal expansion coefficient (α), glass transition temperature (T_g), refractive index (n), transmittance, chemical durability (DR), density (ρ) and the third-order nonlinear optical susceptibility (χ⁽³⁾) were measured and it was found that both components R₂O and MO, have great influence on such properties. Experimental results indicate that alkali metals with small ionic radii improve chemical durability (DR) and mechanical (α, T_g) properties. They also increase n and χ⁽³⁾. Lower thermal expansion coefficient was obtained for Zn and Mg while better chemical durability corresponds to Pb and Zn.
