Module 3: Principles and different parts of optical and electron Microscope (optical, SEM/FESEM, TEM). Secondary and back-scattered electrons. Bright field and Dark field, Contrast mechanism, indexing of electron ring diffraction pattern. Sample preparation, Image interpretation. [10 Hours]
Module 4: Chemical analysis, EDX and WDX, Principle and operation of spectroscopy. [3 Hours]
Module 5: Particle Size Analysis, Surface area and porosity – basic principle and data analysis. [3 Hours]
Course Objectives
- To learn about the basic principles of different instruments used for thermal, structural, microstructural and BET analysis of materials
- To analyze the data obtained from thermal analysis: DTA, DSC, TG, Dilatometer microstructural analysis: XRD, SEM and TEM, and BET analysis.
- The course modules are structured in such a way that it would immensely help students aspiring for higher studies.
