equiatomic

Equiatomic refers to a substance composed of elements in equal atomic proportions. This means that for every atom of one element present, there is an equal number of atoms of another element, and so on, for all constituent elements. The term is most commonly used in the context of alloys or intermetallic compounds where two or more elements combine to form a new material. For example, an equiatomic alloy of copper and gold would contain one copper atom for every gold atom. This precise ratio is often crucial for determining the physical and chemical properties of the resulting material, such as its crystal structure, melting point, hardness, and electrical conductivity. The preparation and characterization of equiatomic compounds are important in materials science and solid-state chemistry, as they can exhibit unique and predictable properties that differ significantly from those of their constituent elements or non-equiatomic mixtures. Studying equiatomic phases helps researchers understand fundamental bonding mechanisms and design new materials with tailored characteristics.
