This is the first comprehensive study on the joining of ceramics using microwave heating and reports on the criticality of the second phase content in the ceramic.
Microwave heating of ceramics is both quick and efficient, and industry is becoming increasingly aware of its potential. However, the microwave bonding of ceramics has received little attention despite the ability to heat ceramics uniformly with minimal stress. Problems associated with the development of the technique are the design and manufacture of microwave heating systems (applicators) capable of bonding ceramics using applied pressure and, if required, an inert atmosphere. This programme, carried out in conjunction with the University of Nottingham, had the aim to design and manufacture suitable applicators for heating and joining ceramics.
- To review previous work
- To design and manufacture a microwave heating system, with force actuation, for bonding ceramics
- To measure the dielectric properties of selected ceramics and to determine the methods required to heat low and high dielectric ceramics
- To develop procedures for microwave bonding of specific ceramics and establish joint properties
- To assess the industrial potential of microwave heating for bonding ceramics
