Abstract

The periclase contains 0.1% wt. B2O3, >=98% wt. MgO, 2-3 moles CaO per mole of SiO2 + Al2O3 + Fe2O3, >=1 mole Fe2O3 per mole Al2O3. all the MgO is present as periclase, all the SiO2 as calcium silicates, all the Al2O3 as brownmillerite all the Fe2O3 as brownmillerite or dicalcium ferrite and the wt ratio of calcium silicates to Fe cpds. is 2:1 to 5:1. Used for refractory bricks.
