Dense liquid silica is also found to have an anomalously high specific heat right above the melting point (fig. S13). The shock temperature along the stishovite Hugoniot increases at a slower rate than predicted by the ANEOS model, which is based on the classical Dulong-Petit limit for the specific heat: C V = 3 nTk B , where n is the nuer of ions and k B is the Boltzmann constant ( 9 , 17

US4131697A - Method of coating carbon filaments with …

Carbon filaments having a coating of silicon carbide up to 0.2 micron or over 10 microns thick are described. A coating of silicon carbide is formed on carbon filaments by passing the heated filaments into an atmosphere of hydrogen and silicon tetrachloride to deposit silicon, and then into a silicon carbide-forming atmosphere.

3D Printed Ceramic is Incredibly Hot Right Now | All3DP

They’ve invented a “pre-ceramic monomer” made from silicon carbide powder, which prints just like any other polymer filament (in a $3,000 incredibly detailed stereolithic system, but still). But when exposed to UV light, the resin cures into a silicon carbide ceramic — which is to say an extremely durable, lightweight, non-conductive material.
