Both Cr2O3 and NiO absorb 28 GHz millimeter-wave energy well and this strong coupling with millimeter-waves can be used to promote a chemical reaction with La2O3 to form perovskite-type LaCrO3 or LaNiO3 ceramics. In La 2O3-Cr2O3 system, the reaction proceeded rapidly and single phase LaCrO3 could be synthesized within 15 min even at lower temperature (∼400°C) as compared to conventional synthesis (T > 800°C). In the case of LaNiO3, the reaction proceeded rapidly in the early stage of heating (t < 15min), but not completed even after prolonged millimeter-wave irradiation. The results suggest an importance of millimeter-wave penetration depth, especially for processing of conductive materials.
