Question

47. HAFNIUM CARBIDE is –

• A. Most heat conducting material
• B. Most magnetic material
• C. Most heat resistant material
• D. Most electricity conducting material

Answer 1

The correct option is C Most heat resistant material

1. A team of UK-based researchers have identified Hafnium carbide (HfC) as the world’s most heat resistant material. It can withstand record melting point temperatures up to 3958 °C (approx. 4000 °C).
2. New Laser-heating techniques were used to find the temperature at which Tantalum carbide (TaC) and HfC melted, both separately and in mixed compositions.
3. This discovery may pave the way for improved heat resistant shielding for the faster-than-ever hypersonic space vehicles. It means that future spacecraft could become more faster than ever
