Carbon in wrought iron is present as_________?

Correct answer: B. Iron carbide

  • A. Silicon carbide
  • B. Iron carbide
  • C. Graphite
  • D. Partly as iron carbide and partly as graphite

Explanation

In wrought iron, the small amount of carbon is conventionally described as being present mainly in combined form as iron carbide, Fe3C. Students may choose graphite because free carbon occurs in some cast irons, but wrought iron is not normally identified by graphite as its carbon form.

About Crystalline Solids

Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
