Question: Name the material which is found to be having highest ever recorded melting point for a material by the Researchers from Imperial College London, U.K.
(d)Tantalum carbide (TaC)
- Recently Researchers from Imperial College London in the UK discovered that the melting point of hafnium carbide is the highest ever recorded for a material.
- It can withstand temperatures of nearly 4,000 degrees Celsius.
- Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily resistant to heat.
- 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.
- The researchers developed a new extreme heating technique using lasers to test the heat tolerance of TaC and HfC.
- The compound TaC melted at 3,768 degrees Celsius, and HfC melted at 3,958 degrees Celsius.
- The recent finding may pave the way for the next generation of hypersonic vehicles, meaning spacecraft could become faster than ever.
