Physical properties study of Sb2O3-PbO-MnO ternary system

Vitreous system based on antimony oxide Sb2O3 has been investigated. The influence of MnO substitution on the mechanical and physical properties in the (80-X) Sb2O3–20 PbO–X MnO system has been studied. Vickers hardness, density, molar volume, Young modulus, glass temperature transition, infrared and UV transmission spectra depend on the MnO concentration. Crack analysis of the glass surface under indentor deformation shows the tenacity changes according to the MnO concentration.
