JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

This course is intended to provide in depth knowledge on processing

ceramic materials including structure, properties, phase transformations, applications, and fabrication methods of ceramics.

Course Outcome

Through this course, the student will be able to compare ceramics and

understand their superiority over metals in some specific and critical applications. The student would also be benefited by understanding the various applications of ceramic materials in real time engineering applications.
