Title: Study on Calcination and Characterization of Rectorite
Abstract: Calcination rectorite(CREC) was obtained using the rectorite from Hubei Zhongxiang Mine.And setting the white degree and the residual sulfur content as the indices,the calcination conditions of rectorite were systematically seeked.Then CREC was characterized and thermally analyzed by XRD,SEM and TG-DTA,etc.The results suggested the optimum calcination condition was that the material granularity was less than 0.050 mm,the calcination temperature was 850 ℃,the rising temperature time was 4 h,the holding temperature time was 4 h.
