Dear Editor,

I would like to submit the manuscript entitled “Mechanical, Structural and Thermal Properties of Transparent Bi2O3-Al2O3-ZnO-TeO2 Glass System”, authored by Idris Kabalci, Erkan Koc, Sirri Semih Ozturk for possible publication in the Journal of Inorganic and Organometallic Polymers and Materials”.

Oxide based optical glass materials has important potential material in many applications from fiber optic to sensor due to the high transparency and amourphous structures. We prepared novel optical glass materials based on the bismuth and aluminum contents to be able to determine the physical, chemical and mechanical properties by considering the systematic experimental steps.

In this study Bi2O3 - Al2O3 based tellurite optical glasses have been prepared by using conventional melt quenching method as a function of the both Bi2O3 and Al2O3 compositions. There is a strong interactions between the glass former and modifier ions that might effect on the structure and mechanical properties.

These findings were not reported previously.

The manuscript is original and it has not been published or submitted to any journal for consideration of publishing.

Sincerely yours,

Dr. Erkan KOÇ
