Flashcards covering crystalline solids, ionic solids, and defects in crystalline solids.

FCC (Face-Centered Cubic)

Cubic structure with atoms at each corner and one in the center of each face.

Vcelda = Nátomos x PA / ρ NAvogadro

Formula to calculate the volume of a cell.

Arista (a)

The cube root of the cell volume.

N° celdas unitarias

Number of unit cells = Volume of lamina / Volume of cell

HCP (Hexagonal Close-Packed)

Crystal structure with a hexagonal arrangement of atoms.

Volume of HCP Cell (VCelda,HCP)

VCelda,HCP = (3 a^2 c√3) / 2

Vacancia (Vacancy)

A point where an atom is missing from its regular position in the lattice.

Átomo Intersticial (Interstitial Atom)

An atom of the same or different type located in the interstitial space of the lattice.

Density Formula

ρ = (NÁtomos * PA) / (VCelda * NAv)

BCC (Body-Centered Cubic)

Cubic structure with an atom at each corner and one in the center of the cube, essential for calculating density with defects.

Átomo sustitucional (Substitutional Atom)

A metal atom replacing a host atom in a crystal lattice.

Punto reticular

Idealized representation of an atom's position within the periodic arrangement of a lattice.

Parámetro de red

Distance between two equivalent points in the crystal lattice, usually between neighboring atoms.

Átomo intersticial

Small atom located in an intermediate site of the network, not occupying normal positions.

Átomo sustitucional

Different atom that replaces one of the original type in a regular position of the network.
