Hafnium Carbide : Environment for UPSC Exams
Hafnium Carbide : Environment for UPSC Exams
- Hafnium carbide (HfC) is a chemical compound of hafnium and carbon. With a melting point of about 3900 °C it is one of the most refractory binary compounds known.
- Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily resistant to heat,
- It is the world’s most heat resistant material, which can withstand temperatures of nearly 4,000 degrees Celsius; the melting point is the highest ever recorded for a material.
- It will pave way for improved heat resistant shielding for hypersonic space vehicles and spacecraft would also become faster than ever.
- Currently, vehicles going over Mach 5 speeds do not carry people.
