Popis: A tailorable viscosity, liquid polysilazane has been developed which thermosets to a solid ceramic precursor for both silicon nitride (Si3N4) and silicon carbide (SiC). Conversion of the thermoset, crosslinked polysilazane to a ceramic material has been examined. Preferential formation of silicon carbide or silicon nitride is controlled by the pyrolysis conditions employed.
