ühe elemendi eksisteerimine kahes või enamas tahkes, vedelas või gaasilises vormis (vrd polümorfism)
Hea teada
Kahe või enama erineva kristallilise vormi esinemine ühekomponentses tahkises. Lähedane sünonüümile polümorfism.
the existence of an element in two or more solid, liquid or gaseous forms, in one phase of matter, called allotropes (compare: polymorphism)
Hea teada
The existence of two or more crystal structures for single-component substances. A near synonym for polymorphism. Generally restricted to describing polymorphic behavior in elements, terminal phases, and alloys whose behavior closely parallels that of the predominant constituent element.
