Microwave Joining of Ceramics,
Abstract
AlOOH gel was used as a bonding layer for alumina samples to be joined. Microwave radiation was used as a source of energy in a multi-mode cavity. The gel was brushed on the surfaces of the substrates to be joined and by applying pressure of 0.6-2 MPa, while heated with microwave energy, joints of different strengths were produced. The maximum strength was achieved at 1650 deg C and it was approximately 93 % of the original strength. It was found that the use of AIOOH gel improves the joint quality for samples joined at relatively low temperature. Our results suggest that bonding occurred due to a diffusion process at the interface.
