Significance of thermal diffusivity
WebBecause thermal degradation and evaporation produce gases, conventional thermal methods require heating rates of approximately 5-10°C/hour so that bubbles and defects do not form in the compact. However, in the wicking method, the most of the binders are removed in the liquid state, so by using this method fewer defects are introduced and … WebThe first four chapters are focus on the use of US alone or in combination with salt blends (NaCl/KCl), to enhance salt diffusion and distribution. Initially, in Chapter 2 the operation parameters of the US system influencing salt uptake are investigated; modifications in moisture and salt content were used to evaluate salt distribution in the samples.
