Several studies have been conducted over the last several years assessing the use of microwave heating for processing reaction-bonded silicon nitride (RBSN) and sintered reaction-bonded silicon nitride (SRBSN). Although SRBSN test specimens up to 500g have been processed by using microwave heating, samples have been limited to simple shapes such as tiles. In this study, microwave packaging techniques were developed to process complex SRBSN parts and multiple samples within a single cycle. Physical and mechanical properties of test samples were measured. Comparison studies were performed using conventional furnace processing to establish baseline values and expected statistical variation.
