Abstract

Starting materials for tungsten production (APT, AMT, WO3·H2O, and stoichiometric and substoichiometric dehydrated deammoniated powders) have been treated with microwave power. The increase in temperature has been registered. Time-temperature plots have been recorded. The temperature slopes in the room-temperature range have been compared with room-temperature dielectric-loss data at microwave frequencies. Some perspectives of microwave powder processing and test methods based on the varying microwave-transparency (dielectric-loss factor) of the materials involved are shown. The microwave calcination of APT is demonstrated. Dehydration process can easily be followed.
