Characterization Techniques
Definition:
Characterization of Materials : It is a process by which
materials structure & properties are probed &
measured.
Characterization Techniques : These are the
techniques of studying the microscopic structure &
properties of the materials
Classification of Characterization
Techniques
Microscopy
Spectroscopy
Microscopy
Definition :
It is a category of characterization
technique which probe and map the
surface and sub-surface structure of the
materials
Instruments of Microscopy
• Optical Microscope
• Scanning Electron Microscope (SEM)
• Transmission Electron Microscope (TEM)
• Field Ion Microscope
• Scanning tunneling Microscope
• X-ray Diffraction Topography (XRT)
•Atomic Force Microscope (latest)
Spectroscopy
Definition :
It is a category of characterization
technique which reveal the chemical
composition ,composition variation ,crystal
structure & photo-electric properties of the
materials.
Instruments of Spectroscopy
• Energy-Dispersive X-ray spectroscopy
• Wavelength-Dispersive X-ray spectroscopy
• X-ray Diffraction
