Synthesis diagram and electromagnetic wave absorption properties of SiOC@C ceramic nanospheres

Caption

SiOC@C ceramic nanosphere precursor was obtained using a liquid phase method. Then, a series of SiOC@C ceramic nanospheres containing SiC/Si3N4, free carbon, and amorphous SiOC were successfully obtained through rational control of the heat-treatment temperature and atmosphere. Intriguingly, the SiOC@C ceramic nanospheres obtained in the Ar atmosphere exhibited the minimum reflection loss value of -67.03 dB; and the SiOC@C ceramic nanospheres obtained in the N2 atmosphere exhibited the minimum reflection loss value of -62.76 dB.
