内容简介

The chemical composition and microstructure of Tibetan microcrystalline magnesite were studied by means of XRF, XRD and FESEM. It is found that the microcrystalline magnesite has uniformly distributed grains, mostly in the range of 2-4 μm, and the MgO content is 47.80%. In fused magnesia, the druses are colorless transparent periclase megacrysts without impurity, while the crust sand is white, with a high MgO content up to 97%99%. The periclase crystals are big, appearing as faced and step-growth morphology. Massive secondary long columnar periclase is crystallized.
