| Abstract Scope |
Silicon carbonitrides (SiCNs) have gained interest as an engineering ceramic due to their high hardness, good oxidation, and good creep resistances at high temperatures. Most bulk SiCNs are made from pyrolysis of polymer precursors to form an amorphous powder followed by consolidation via sintering at high temperatures. These high temperatures result in crystallization of amorphous SiCN into a SiC/SiN composite, leaving few reports on the properties bulk amorphous SiCN. This work looks to create bulk amorphous SiCN from gaseous precursors through a combination of nonthermal plasma synthesis to form amorphous SiCN nanoparticles and spark plasma sintering to consolidate into a bulk amorphous form. By altering the ratios of the gaseous precursors in plasma synthesis, the resulting structural properties of SiCN are reported at various compositions. |
