byproducts complicates the carbothermic reduction and chlorination process. The thermodynamic study of chemical reactions provides a basic understanding of the process prior to designing suitable reaction...-solid reaction, gaseous products are generated when the carbothermic reduction reaction takes place. In vacuum, gaseous products are removed continuously through pump, which can accumulate the chemical......

in the undrained shear strength is mainly caused by a reduction in water content or by the water content reduction–cementing reaction [32]. The cementing reaction mainly occurs due to the chemical reaction... strength increase came from the reduction in water content and the production of cementing material in the electro-osmotic chemical experiment near the cathode [17]. The water content of E_1_4 was higher......
