During heating,phase transformation and expansibility of the new quartz sands and the calcined Quartz sands from two places were determined by DSC and thermodilatometry.
Thermal dynamical analysis on the calcine system of cement-precalcination kiln in Shangdong Lunan Cement Ltd.Co. was made in this paper, exergy and its analytical method were introduced.
The IR spectra of hydrogel, alcogel and aerogel of BaFe12O19 were studied, and the ones of the powders calcined at different temperatures for different time were also studied.
