 Reactive magnesia (rMgO) is also variously known as caustic calcined magnesia, caustic magnesia or CCM. The temperature of firing has a greater influence on reactivity than grind size as excess energy goes into lattice energy.
Technical information about reactive magnesia is available in the technical area of our web site.
