We are constantly updating web pages, writing papers and preparing presentations as there is so much to communicate and so much misinformation to correct. More up to date papers on the TecEco web site should also be consulted as they are more authoritative about our technologies that third party sources.\

[1] 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.
