An example of interstitial carbide among the following is:
Open in App
Solution
The correct option is B CaC2
Interstitial carbides are derived primarily from relatively large transition metals that act as a host lattice for the small carbon atoms, which occupy the interstices of the close-packed metal atoms. Interstitial carbides are characterized by extreme hardness but at the same time extreme brittleness. They have very high melting points (typically about 3,000–4,000 °C [5,400–7,200 °F]) and retain many of the properties associated with the metal itself, such as high conductivity of heat and electricity as well as metallic lustre
