A new method of preparing anhydrous magnesium carbonate (MgCO3) under high pressure and its thermal property

It shows the SEM image of MgCO3 micro-particles. It can been seen clearly that the as-synthesized MgCO3 consists of the various size of micro-particles and the maximum size of micro-particles exceeds to 100 μm. It makes possible, in this case, to perform the micro-characterization on single micro-particles, such as micro Raman spectrum and electron probing micro-analysis. Subsequently, the high quality MgCO3 single crystal growth could be attempted in the further.194
