Thanks for highlighting. @Lalit.

Lime is the correct answer.

Yes, the answer is Magnesium oxide.

I think lime is not a chemical ingredient, so the answer is magnesium oxide.

Lime (CaO) 60 to 67%
Silica (SiO2) 17 to 25%
Alumina (Al2O3) 3 to 8%
Iron oxide (Fe2O3) 0.5 to 6%
Magnesia (MgO) 0.1 to 4%
Sulphur trioxide (SO3) 1 to 3%
Soda and/or Potash (Na2O+K2O) 0.5 to 1.3%
