  • Abstract This study shows that there exist three universal and unique phase diagrams to describe general development of the pore shape in solid. Like thermodynamics, phase diagrams have advantages to generally identify the states and design processes of a system. In this study, three phase diagrams are found to be under dimensionless coordinate systems of dimensionless apex radius, contact angle, and base radius of the bubble cap, as well as solidification rate, contact angle, and growth rate of base radius. The computed results of the development of the pore shape agree with experimental data. The pore shape in solid thus can be optimistically predicted and controlled by choosing a desired path on phase diagrams.
