Dear friend Kaushal Kumar Sarswat,

I hope this message finds you Kaushal Kumar Sarswat well! I wanted to share some insights regarding the terminology used in thermogravimetric analysis (TGA) of chalcogenide glasses, particularly focusing on the concepts of mass loss. In this context, "evaporation" and "volatilization" are often the most accurate terms to describe the processes occurring in these materials.

Chalcogenide glasses exhibit unique properties, such as forming glassy phases at lower temperatures than oxide glasses. During TGA, mass loss can result from the volatilization of components like sulfur, selenium, or tellurium, which have relatively high vapor pressures at elevated temperatures. This is where the terms come into play:

Evaporation refers to the escape of atoms or molecules from the surface into a gaseous phase, which is precisely what happens with volatile components in chalcogenide glasses.

Volatilization describes the transformation from solid or liquid to gas, capturing the overall mass loss process due to high temperatures, making it particularly relevant for our studies.

For further reading, I recommend checking out the work of B.G. Kolomiets and A.E. Ivanova on chalcogenide glass properties, as well as articles in journals like the "Journal of Non-Crystalline Solids" or "Physics and Chemistry of Glasses: European Journal of Glass Science and Technology Part B." These resources delve into the thermal behavior of chalcogenide glasses and can provide valuable insights into TGA processes.

I hope you find this information helpful for your studies! If you have any questions or need further clarification, feel free to reach out.

Best regards,

Kaushik

Thank you Kaushik Shandilya sir, definitely i will share the problems related to research field.

firstly you must know your component very well secondly you need FTIr parallel work together and which group of spectate of your material you can see and know

there for you know what you want to know
