multisalt

Multisalt is a term encountered in several scientific fields to describe systems that contain more than one salt. It is not a formal, standardized concept with a single definition; its precise meaning depends on the context, discipline, and the properties of interest.

In chemistry and crystallography, multisalt can refer to solids in which two or more distinct salt moieties are present within a single crystal lattice, such as double or triple salts, or to solid solutions where different salt ions substitute for one another. In solution, multisalt describes mixtures that contain several different ionic salts dissolved together, with ion–ion interactions influencing solubility, complexation, and speciation.

In materials science and energy applications, multisalt concepts are used when several salts are combined to exploit synergistic effects on ionic conductivity, thermal stability, or electrochemical performance. Multisalt electrolytes or molten-salt systems are studied for their potential in high-temperature batteries and related technologies, with performance linked to the choice, ratio, and interactions of the constituent salts.

In agriculture, horticulture, and food science, multisalt can describe blends of fertilizer salts or curing salts designed to deliver multiple nutrients or functional properties. Across uses, the term signals a composite or mixture rather than a single salt species.

Because multisalt is not standardized, researchers typically specify the exact salts, their stoichiometry, phase behavior, and context to avoid ambiguity.
