Related facts:

  • On 30 December 2016; The Cochin Shipyard Limited (CSL) has delivered ICGS AYUSH, the 20th Fast Patrol Vessel (FPV) to the Indian Coast Guard.
  • With this, CSL has completed construction of 20 FPVs for the Indian Coast Guard.
  • It should be known that CSL was awarded the work of constructing 20 Fast Patrol Vessels for the Indian Coast Guard on 20th Oct 2010.
  • CSL delivered the first vessel on 25th Sept 2013 and subsequently delivered vessels in about two months interval.
  • CSL started delivering vessels ahead of schedule from the 13th vessel onwards.
  • ICGS AYUSH, the 20th Fast Patrol Vessel, the last in the series (CSL Yard No BY 520).
  • ICGS Ayush will be operated from the Coast Guard Station at Krishnapatnam.

  • The Indian Coast Guard was formally established on 18 August 1978 by the Coast Guard Act, 1978 of the Parliament of India as an independent Armed force of India.
  • It operates under the Ministry of Defence.
  • The Indian Coast Guard operates in following five regions:
    1. Western Region (W)-Mumbai
    2. Eastern Region (E)-Chennai
    3. North-East Region (NE)-Kolkata
    4. Andaman & Nicobar Region (A&N)-Port Blair
    5. North-West Region (NW)-Gandhinagar
  • Indian Coast guard is responsible for following work :
    1. EEZ (Exclusive Economic Zone) security
    2. Coastal and Offshore Security
    3. Marine Environment Protection
    4. Scientific Support

World's most heat resistant material

World’s most heat resistant material

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.
(a)Hafnium carbide
(b)Silicon carbide
(c)Calcium carbide
(d)Tantalum carbide (TaC)
Ans: (a)
Related facts:

  • 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.
