Syllabus
Experiments for Ceramography and Microscopy Laboratory:
1. Ceramography specimen preparation I: Sectioning and sawing, mounting of samples.
This session involves the initial preparation of ceramic samples for microscopy, including sawing of bigger samples using motorized blades, sectioning of the samples. Different methods in resin-based mounting and curing of samples will be conducted.
2. Ceramography specimen preparation II: Grinding, polishing, lapping, etching.
This session involves working with the cured sample mounts for subsequent grinding, polishing, and lapping operations using various grit size of abrasives. Further, chemical and thermal etching of the polished samples will be conducted.
3. Microscopy: Basic principles and demonstration of optical microscopy, scanning electron microscopy.
Basic principles of optical microscopy will be discussed and demonstrated for the imaging of polished specimens with micron-sized grains. Basics of scanning electron microscopy shall be discussed and its usability for fine grained samples.
4. Quantitative ceramography: Grain size determination, shape, anisotropy, porosity and second phase calculation.
Micrographs obtained from optical/electron microscopy shall be used to compute average grain size, anisotropy, and porosity/second phases with the use of software tools and manual methods.
5. Microscopy of oxide ceramics: Al2O3, ZrO2, MgAl2O4.
Dense engineering ceramic samples will be analyzed.
6. Microscopy of industrial ceramics: Refractories, Triaxial bodies.
Industrial ceramic samples, such as single and multi-phase refractories, triaxial bodies.
7. Microscopy of non-oxide ceramics: SiC/Si3N4/B4C/SiAlON.
Non-oxide ceramics, which are typically hard and follow a different set of precedures, will be demonstrated and hands-on experiments conducted.
