Abstract

Decomposition of the mixed carbonate mineral dolomite, CaMg(CO3)2, and formation of CaO/MgO nanopolycrystals were observed in situ using a field emission scanning electron microscope with a not stage. The pyrolysis benavior of dolomite was studied with an in situ high-temperature X-ray powder diffraction technique. Nanosized particles formed during pyrolysis then sintered into CaO/MgO nanopolycrystals. Dense bulk-form CaO/MgO and CaZrO3/MgO nanocomposites were successfully fabricated using reactive hot-pressing from dolomite and dolomite/zirconia mixed powders, respectively.
