## What is the relation between lattice constant and density?

The mass densities of crystalline materials are related to their crystal structures: (a) The lattice constant for crystalline Si is a = 5.43 Å, i.e., 5.43•10-10 m. Prove that its mass density is 2.33 gr/cm3. (b)Gem diamonds consist of pure carbon in the face-centered cubic (fcc) crystal structure.

How do you calculate lattice parameters?

Calculate the lattice constant, a, of the cubic unit cell. If the space lattice is SC, the lattice constant is given by the formula a = [2 x r]. For example, the lattice constant of the SC-crystallized polonium is [2 x 0.167 nm], or 0.334 nm.

### What is the distance between two 111 planes?

Calculate the distance between 111 planes in a crystal of Calculate the distance between 111 planes in a crystal of Ca. the answer is. =0.321 nm.

What is the FCC lattice structure of germanium?

Germanium has the diamond cubic crystal structure shown, an fcc lattice with a basis of two germanium atoms, one at (0,0,0) and the other at (1/4, 1/4, 1/4) in units of the cube edge. It can also be visualized as two interpenetrating fcc lattices of germanium atoms with their origins displaced by (1/4, 1/4, 1/4).
