Abstract
Magnesia (MgO) or the mineralogical term “periclase” was firstly synthesized by heating of magnesium carbonate (MgCO3) in 1754. The article gives a survey on the industrial use of magnesia as refractory material and an historical overview on the application of basic brick grades in cement rotary kilns. The current stresses on basic refractory linings in cement rotary kilns are outlined. Prospects for future R+D work are given.
Keywords
