* PhD: A PhD is generally research-focused. Your MSc in Industrial Chemistry provides a good foundation for a PhD in chemistry, chemical engineering, materials science, or related fields. The specific area of research will depend on the availability of supervisors and projects at universities.
* M.Tech: An M.Tech (Master of Technology) is a more specialized, technology-focused postgraduate degree. Whether you're eligible depends on the specific M.Tech program. Some programs might require a background in chemical engineering, while others might accept an MSc in Industrial Chemistry if your coursework includes relevant subjects. You might need to take bridging courses to fill any gaps in your knowledge.
In short: A PhD is a viable option following an MSc in Industrial Chemistry. An M.Tech might also be possible, depending on the program requirements. You should research specific PhD and M.Tech programs that align with your interests and check their admission requirements carefully.
