In this study, dehydration of sodium carbonate monohydrate (Na2CO3·H2O) (SCM) in a microwave (MW) field with silicon carbide (SiC) as an indirect heating medium was investigated. SCM samples containing up to 3% free moisture were placed in the microwave oven. The heating experiments showed that SCM is a poor microwave energy absorber for up to 6 minutes of irradiation at 800 W of microwave power. The heat for SCM calcination is provided by SiC, which absorbs microwave energy. The monohydrate is then converted to anhydrous sodium carbonate on the SiC plate by calcining, which involves removing the crystal water through heating of the monohydrate to temperatures exceeding 120 °C. This calcination results in a solid phase recrystallization of the monohydrate into anhydrous form. Furthermore, the process demonstrated that dehydration of SCM, in the context of indirect heating, can be accelerated by increasing the microwave field power.
