摘要:
A method of producing silicon nitride ceramics and silicon nitride ceramic composites. A mixture comprising a polysilazane and an additive effective to increase coupling between the mixture and electromagnetic energy is converted to a preceramic intermediate. The preceramic intermediate is treated with electromagnetic energy and thereby converted to a silicon nitride ceramic and/or a silicon nitride ceramic composite.
