A new method for the kinetic analysis of the initial stage of sintering for constant-heating-rate data has been proposed. Unlike all of the methods previously reported in the literature, this new method proposed here allows the simultaneous determination of the activation energy and the kinetic model from a single dilatometric curve recorded under a linear-heating-rate program. The proposed method has been tested with simulated sintering curves and experimental results have been obtained for the sintering of a rutile sample. 相似文献

A new method for the extraction of chrome mordant dyes from wool has been investigated. The method, which involves the use of EDTA in aqueous dimethylformamide, extracts sufficient dye for use in chromatographic identification. The applicability of the method has been studied with eleven selected chrome mordant dyes. 相似文献

A new method for the calculation of the weight-average molecular weight from low-angle laser light scattering data has been developed which only requires the measurement of the Rayleigh factor at a single concentration. The method requires the knowledge of the dependence of the second virial coefficient on molecular weight and has been applied to polyacrylamides ranging in molecular weight from 10,000 to 9,000,000. The new method improves the accuracy of light scattering measurements to ±4.7% compared with ±11.2% for the conventional procedure and requires only one-fourth the time. The effect of polydispersity has been included in the procedure. The method is general and is recommended for all linear polymers. 相似文献
