Microwave hybrid heating (MHH) was used to join 99.5% pure alumina pieces 25 mm diameter and 25 mm long using 94% pure alumina as the interlayer material. The interlayer material was cut from a rod into discs approximately 2 mm thick.
Joining was performed in a home model microwave oven. Temperatures for joining ranged from 1450 °C to 1550 °C and pressures from 1–3 MPa. For comparison, similar joints were made in a conventional furnace.
Joined specimens were tested using four-point bend at room temperature. Statistical analysis was utilized to determine the relative effect of the different processing parameters on the strength of the joint.
