Magnesite Magnesite is a rare earth mineral. It can be used to provide excellent refractory materials for the steel sector, beneficial agricultural and livestock appliions and innovative products for the environment, given the fact that its derivatives are vital for environmental restoration.
The research team developed the new age-hardenable magnesium alloy by adding very small amounts of zinc, manganese, aluminum and calcium. The alloy has excellent room temperature formability comparable to that of medium strength aluminum alloys that are used in some automobile bodies, and it’s also stronger and less expensive to process.
