Highlights

• The thermal behavior and structure of solid solutions between anthracene and phenanthrene were investigated.

• The formation of solid solutions was demonstrated from the aspect of lattice energy deviation.

• The morphology of solid solutions similar to their host components and change with the mixture of guest parts.

• Crystallization process were described with population balance model.


Abstract

We explored such issues as the formation mechanism, structure and propriety of the solid solutions of anthracene (ANT)–phenanthrene (PHE). Solution crystallization and solid-state grinding were employed to prepare solid solutions under different conditions. The thermal behavior and PXRD scanning results revealed the formation of discontinuous solid solutions, whose melting points and crystal lattices varied linearly with mixed ratio. Combing with Materials Studio, the formation possibility of solid solutions were investigated by evaluating the change of the energy. The crystal morphology of the solid solutions have a positive correlation with the change of the major part. Finally, the solution crystallization process of solid solution were studied using the population balance model.
