Which of the following is neutral refractorie material?

Options

  1. ASiO ₂
  2. BMgO
  3. CCaO
  4. DSiC

Correct answer

D. SiC

Step-by-step solution

Substances which resist high temperatures and do not become soft are called refractories material. The neutral refractories are graphite, chromite and carboren, dum ( SiC ). Acidic refractories are SiO ₂ , basic refractories are CaO and MgO.
