Definition

Meaning and Definition

A solid material composed of two or more substances whose atoms or molecules share a single crystal lattice.

A single, homogeneous crystalline phase containing more than one chemical component, formed either by substitution of atoms in the lattice or by occupying interstitial sites. In a broader sense, it can metaphorically describe any hybrid system or entity composed of distinct, integrated elements.

Dialectal Variation

Differences

No significant differences in meaning or usage. Spelling of related terms follows regional conventions (e.g., 'crystalline' vs. 'crystalline' is same; 'metallurgy' vs. 'metallurgy').

Connotations

None beyond the technical definition.

Frequency

Equally low and specialized in both variants.

Common Mistakes When Using “mixed crystal”

  • Using 'mixed crystal' to describe a physical mixture of different pure crystals (e.g., salt and sugar grains).
  • Confusing it with a 'doped crystal' where trace amounts of another substance are added.
  • Assuming it is a common, everyday term.

FAQ

Frequently Asked Questions

In the context of metals, an alloy is a type of mixed crystal (specifically a solid solution). However, 'mixed crystal' is a broader term applying to any crystalline substance with multiple components in a single lattice, including ionic salts and semiconductors.

No, not by simple physical means like filtering. Because the components are integrated into a single atomic-scale lattice, separation requires chemical or electrochemical processes to break the crystal structure.

Doping typically refers to the intentional addition of very small (trace) amounts of an impurity to modify properties. A mixed crystal implies significant, often variable, proportions of two or more primary components forming the main structure.

Yes, they are classic examples. A ruby is a mixed crystal of aluminium oxide (corundum) with trace chromium ions substituting for some aluminium ions in the lattice, giving the red colour.

A solid material composed of two or more substances whose atoms or molecules share a single crystal lattice.

Mixed crystal is usually technical/scientific in register.

Mixed crystal: in British English it is pronounced /ˈmɪkst ˈkrɪstəl/, and in American English it is pronounced /ˈmɪkst ˈkrɪstəl/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Imagine a CHRISTMAS (crystal) cake that is a MIX of fruits and nuts, but baked so perfectly that every slice contains the same blend, just like atoms in a mixed crystal lattice.

Conceptual Metaphor

A UNIFORM TEAM OF DIFFERENT PLAYERS (where individual players (atoms/molecules) of different types are organised into a single, cohesive structure (the lattice) with shared rules).
