DOLOMITE-BASED MATERIAL HAVING HIGH SPECIFIC SURFACE AREA, A METHOD FOR PREPARING THEREOF, A METHOD FOR CONTROLLING A QUALITY THEREOF, AND A METHOD FOR ADSORBING HEAVY METAL, HALOGEN AND METALLOID |
| 摘要 |
A dolomite-based material having a high specific surface area of the present invention is half-fired dolomite in which a content of a residual CaMg(CO3)2 phase in the half-fired dolomite, which is analyzed using a Rietveld method by means of powder X-ray diffraction, is 0.4δ×δ35.4 (wt %), and, when the content of the residual CaMg(CO3)2 phase in the fired-dolomite is maintained at 0.4δ×δ35.4 (wt %), the dolomite-based material maintains quality of having a high specific surface area. |
