Crystals Flashcard

Front

What are interstitial defects in crystals?

Back

Interstitial defects occur when a new unit cell is placed in between two unit cells in the repeating arrangement.

Front

What are substitutional defects in crystals?

Back

Substitutional defects occur when one unit cell is replaced by a different unit cell in the repeating arrangement.

Front

What is a vacancy defect?

Back

A vacancy defect occurs when a unit cell is missing from the repeating arrangement.

Front

What are the two types of defects responsible for creating alloys?

Back

Interstitial and substitutional defects.

Front

What factors determine the shape and size of a crystal?

Back

Internal symmetry and growth rates.

Front

What is a point defect in crystals?

Back

A point defect is a localized disruption in the crystal lattice, such as a vacancy or interstitial defect.

Front

What is a line defect in crystals?

Back

A line defect is a one-dimensional defect in the crystal lattice, such as a dislocation.

Front

What is an interfacial defect in crystals?

Back

An interfacial defect occurs at the boundary between two different crystal structures or phases.

Front

How do growth rates affect crystal formation?

Back

Growth rates influence the size and shape of crystals, as faster growth can lead to irregular shapes.

Front

What is the significance of symmetry in crystal structures?

Back

Symmetry in crystal structures determines the overall shape and properties of the crystal.
