A mechanism theory of dissolution profile of oxide particles in oxide melt
Changji Xuan, Wangzhong Mu
Abstract
Abstract The shape origin and variation of oxide dissolution profile in the oxide melt is for the first time explained with a mechanism of diffusion‐distance‐controlled dissolution (DDD). A novel analytical model is derived to present this theory. The profile shape is governed by the diffusion distance of the dissolved components in the oxide melt. The viscosity gradient at the boundary of the diffusion region provides the driving force for the profile variation. Both temperature and initial viscosity of oxide melt are the key factors determining the oxide dissolution kinetics. This theory can be applied to describe diffusion‐limited particle dissolution in a general system.
