In this article, we report a simple technique for synthesizing spherical non‐oxide silicon carbonitride ceramic particles from a polysilazane precursor. In this technique, the spherical particles of the polysilazane precursor were synthesized first via a precipitation polymerization process and then converted to ceramic particles by pyrolysis. The resultant ceramic particles exhibited a close‐to‐perfect spherical shape and a narrow size distribution around 430 nm. The precipitation and pyrolysis processes were characterized using SEM , TEM , FTIR , and XRD to illustrate the formation mechanisms of the ceramic particles.
