Abstract : Simultaneous sintering and joining of ceramics, often referred to as green state joining, is used in producing structural and electronic composites as well as complex-shaped ceramic components. In this paper, a novel idea of using microwave energy to simultaneously sinter and join ceramics is proposed. Alumina green samples are fired and joined in a single mode microwave heating device. Scanning Electron Microscope and Scanning Acoustic Microscope are used to evaluate joining interface. Experimental results show that, because microwaves offer rapid and uniform heating, fast densification and excellent joining can be achieved.
