        PAVING THE WAY IN CERAMICS

        Researchers at the Centre for Advanced Structural Ceramics at Imperial College London are carrying out world leading research into structural ceramics in a range of areas, including materials that could be used in the aerospace industry,

        In 2016 PhD student Mr Omar Cedillos has shown that Ultra High Temperature Ceramics (UHTCs) Hafnium Carbide & Tantalum Carbide can withstand temperatures of more than 4050°C rather than the previously reported 3950°C.

        such as in heat resistant shielding for the next generation of Hypersonic space vehicle

        For Parker solar probe they using  Thermal protection & Cooling system.ofcourse they using Tungsten also.

        The TPS was designed by the Johns Hopkins Applied Physics Laboratory, and was built at Carbon-Carbon Advanced Technologies, using a carbon composite foam sandwiched between two carbon plates. This lightweight insulation will be accompanied by a finishing touch of white ceramic paint on the sun-facing plate, to reflect as much heat as possible. Tested to withstand up to 3,000 F (1,650 C), the TPS can handle any heat the Sun can send its way, keeping almost all instrumentation safe.

        More detail: Regarding Parker solar probe

      Carbon - carbon composite is used generally high temperature application like solar probe because of it's high temperature resistance and  chemical inertness with environment.

      It is always a coating on high temperature material to withstand the temperature. For example, SiC is coated on steel surface.
