Mineral compositions of the heated coal fly ash
석탄회의 가열에 따른 광물조성 변화
Abstract
In order to clarify the part of thermal properties of coal fly ash, the change of mineral compositions of the heated coal fly ash was investigated by XRD, TG - DTA and SEM. It was found that the mineral composition of coal fly ash was quartz, mullite and glassy phase ( a b. 20 ~ 25 wt % ), and had no difference in the range of 105 to
석탄회의 성상 해명의 일환으로서, 석회석의 열처리 조건과 광물조성의 관계를 검토했다. 석탄회의 주 광물조성은 mullite, quartz 및 유리상(약 20 ~ 25wt%)이었으며,
