The concentration series of nonstoichiometric crystals Ca1–xYxF2+x (x = –) was obtained from a melt by directional crystallization to refine the composition of the temperature maximum on the melting curves. A precision (±9 × 10−5 Å) determination of lattice parameters of the Ca1–xYxF2+x crystals with the structure of fluorite (sp. gr. Fm3m) was performed, and a .

Melting point is the temperature at which a given solid material changes from a solid state to a liquid, or melts. As the mechanism or rate of chemical degradation of a drug is likely to be different in solid and liquid state, melt of the API or any formulation ingredient should be prevented during an APS study of a solid drug substance or formulation by gathering the melting points of the API ...
