Particularly, microwave sintering represents an interesting opportunity at consolidating advanced ceramic materials with a reduced processing time and energy consumption by utilizing electromagnetic radiation to provide high-enough temperatures that allow full densification of the material.
200591High-temperature processing (>800°C, or 1470°F) of materials such as cemented carbides, powder metals, composites and ceramics can be carried out routinely with a new and innovative continuous sintering process that uses microwave energy. The continuous process has been developed commercially to sinter cemented tungsten carbide (WC).
The emerging reduction technologies for titanium from ore produce powder instead of sponge. Conventional methods for sintering and melting of titanium powder are costly, as they are energy intensive and require high vacuum, 10-6 Torr or better, since titanium acts as a getter for oxygen at high temperature, adversely affecting mechanical properties.
Microwave radiation can heat tantalum to 1300-2000℃ for high temperature ceramic sintering. Wavelane microwave sintering furnace is widely suitable for the drying, curing, thermal decomposition, calcination, roasting, synthesis, sintering, and heat treatment of a wide variety of materials.
This Microwave Atmosphere Sintering Furnace is a typical microwave test station with such advantages, such as rapid heating speed, high efficiency, and can make machined material in well consistency.

Microwave ovens requires minimal ramp-up to setpoint temperature and the process has less thermal lag. Further, when cure is complete there is no heat loss due to cool-down when the oven shuts off. Microwave curing occurs with an overall energy efficiency of about 50% relative to the 10% to 30% achieved with fuel-fired processes.
This enhances the sintering process and decreases sintering active energy and densification temperature. Microwave heating also has the potential for energy and cost savings when compared with conventional heating. Zirconia-toughened alumina (ZTA) has received attention for its rapid densification in a microwave furnace.
