Abstract
Decomposition of the mixed carbonate mineral dolomite, CaMg(CO3)(2), a nd formation of CaO/MgO nanopolycrystals were observed in situ using a field emission scanning electron microscope with a hot stage. The pyr olysis behavior of dolomite was studied with an in situ high-temperatu re X-ray powder diffraction technique. Nano-sized particles formed dur ing pyrolysis then sintered into CaO/MgO nanopolycrystals. Dense bulk- form CaO/MgO and CaZrO3/MgO nanocomposites were successfully fabricate d using reactive hot-pressing from dolomite and dolomite/zirconia mixe d powders, respectively.
