Scientists find material that can withstand 4000 degrees Celsius

Scientists have identified materials that can withstand temperatures of nearly 4,000 degrees Celsius.
●    It may pave the way for improved heat resistant shielding for the faster-than-ever hypersonic space vehicles. 
●    Researchers from Imperial College London in the UK discovered that the melting point of hafnium carbide is the highest ever recorded for a material.
●    Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily resistant to heat. 
●    Their ability to withstand extremely harsh environments means that refractory ceramics could be used in thermal protection systems on high-speed vehicles and as fuel cladding in the super-heated environments of nuclear reactors.
●    However, there has not been the technology available to test the melting point of TaC and HfC in the lab to determine how truly extreme an environment they could function in.
