CT9038 MICROWAVE PROCESSING OF CERAMICS L T P C3 0 0 3AIMThe course is aimed to enable the students to the basic concepts about processing the<strong>ceramic</strong> materials in microwave atmosphere.OBJECTIVESOn completion of the course the students are expected to Have learnt the introduction about microwave processing. Have learnt the concepts of microwave heating circuit. Have learnt the applicator types of microwave. Have studied the industrial applications of microwave processing. Have studied the hazard and safety of microwave processing.UNIT I INTRODUCTION 9Dielectric Behavior of materials- power dissipation- propagation factor and skin depth- heatand mass transfer phenomena- temperature distribution- wall loss.UNIT II MICROWAVE HEATING CIRCUIT 9Power sources- klystron and magnetron- operating characteristics- protection system- highfrequency breakdown phenomena- automatic control of the process- automation, tuning andmachining.UNIT III APPLICATION TYPES 9Travelling wave applicators- multimode applications- power transfer- uniformity of heating.UNIT IV INDUSTRIAL APPLICATIONS 9Microwave drying- microwave sintering- application to laboratory models and pilot systemcomparisonwith pilot heating.UNIT V HAZARDS AND SAFETY 9Exposure standards- industrial- frequency band- leakage from industrial equipment- batchsystem- continuous flow system- safety precautions.TOTAL: 45 PERIODSTEXT BOOKS1.
