WET MECHANOCHEMICAL PROCESSING OF CELESTINE USING (NH4)2CO3

Wet Mechanochemical Processing of Celestine using (NH4)2CO3

In this study, traditional (univariate) Tips method of processing to the wet mechanochemical treatment were applied to obtain both SrCO3 and (NH4)2SO4 from celestite (SrSO4)-(NH4)2CO3-H2O mixtures in a planetary ball mill.X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and chemical analysis were used to ana

A comparison between nonlinear and constant thermal properties approaches to estimate the temperature in LASER welding simulation

The nonlinear thermophysical properties significantly affect the temperature field and the appearance of the weld bead in the LASER Beam Welding (LBW).Then, it is vital to have a well-defined numerical model for NEFF N70 KI1513F30G Integrated Tall Fridge analyzing the thermal behavior of the welded material.Nonetheless, many papers still address th
