Thermal Processing of Ceramics
Catalog Data:
Ceramic drying and firing processes. Emphasis is on microstructure development: calcining, solid state sintering, liquid phase sintering, grain growth, hot pressing, and reaction bonding. Sp Qtr.Elective.
Prerequisites:
MSE 616 or permission of the instructor.
Time Distribution:
3-48 minute lectures per week
Objectives:
The student will become acquainted with the concepts of drying, debindering, sintering, and grain growth as applied to ceramic materials. Detailed mechanisms will discussed in qualitative and semi-quantitative way in addition to guidelines on how to design a modern ceramic thermal process. This will enable the student to solve production problems and gain experience in advanced thermal process design. Meet ABET Criteria 3 Outcomes a, c, e, i, and k.

Engineering Design: 1.5 credits or 50%.
Design Component Content:
In lectures students learn how to formulate temperature-time programs for temperature and atmosphere to convert green (unfired) ceramic bodies into the final states. These formulations are based in insights in equilibrium thermodynamics and transport mechanisms. In addition guidelines are provided for selecting of the furnace type, temperature sensors, heating, and construction materials.
Relation to Program Objectives:
1. This course covers fundamental concepts in fluidum transport in porous systems, combustion and calcinations reactions, gas-solid reaction thermodynamics, and sintering mechanisms.
2. Students have the opportunity to apply fundamental concepts in practical situations as occur in thermal processing of ceramics.
3. Students have the opportunity to understand the relationships between the initial green state and the processing method to realize a final shape and micro-structure, and some some extent the consequences for structural and functional properties.
4. This course prepares students for graduate research and employment in the area of materials manufacturing by particulate routes, process design, and materials science and engineering.
Academic Integrity, Academic Misconduct
Academic misconduct may be found in any action that tends to distort the accurate assessment of any student’s individual accomplishments that are evaluated for the purpose of grading or conferring academic credit. Note that a student may be guilty of academic misconduct, for example, by cheating, collaborating, plagiarizing, or by allowing another student to cheat, collaborate, or plagiarize. Note also that the distortion applies, for example, to exams, homework assignments, and laboratory work. To the extent that any class activity (for example: attendance or participation) is used for evaluation for the purpose of grading or conferring academic credit, falsifying or distorting such activity, or permitting another student to falsify or distort such activity, represents academic misconduct.
Additional guidance about what represents academic integrity and misconduct, and related university-wide policies and procedures are available at the following locations:
http://oaa.osu.edu/coam/faq.html
http://oaa.osu.edu/coam/ten-suggestions.html
Course-specific exceptions or amplifications to the departmental and university statements outlined above will be provided by the faculty instructor in writing, preferably as part of the course syllabus.
Note: Students should not request nor accept guidance on these matters from a teaching assistant, fellow student, or anyone other than the faculty instructor of record for this course.
Disabilities Statement
Any student who feels s/he may need an accommodation based on the impact of a disability should contact the Office for Disability Services at 614-292-3307 in room 150 Pomerene Hall to coordinate reasonable accommodations for students with documented disabilities.
