摘要
Microwave heating behavior of various ceramic components was studied using a multi-mode microwave heating equipment operating at a frequency of 28 GHz. Many transition metal oxides and some semiconducting p-block oxides strongly absorb 28 GHz microwaves. These materials can be heated rapidly under microwave irradiation and the resultant heat can be used to drive a chemical reaction with other components. Examples of the synthesis of various complex oxides by 28 GHz microwave irradiation are given. The process sometimes brings unexpected products as a result of microwave-material interaction.
