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

Hafnium Tantalum Carbide - ALB Materials Inc

Tantalum hafnium carbide (Ta4HfC5) is a 4-to-1 ratio of TaC to HfC with an extremely high melting point of 4215 K (3942˚C), which is the highest melting point of all currently known compounds. Due to the properties of these carbides, they are considered candidates for extremely high-temperature appliions such as rocket nozzles and scramjet components, where the operating temperatures can
