WebIn the tetragonal system, like the orthorhombic system, the conventional unit cell is a parallelepiped, but two sides are equal, so that a = b and c = a, while α = β = γ = π/2, and this is a special case of the orthorhombic system. The primitive vectors of the conventional unit cell are A1 A2 A3 = = = ax^ ay^ cz^. There are four orthorhombic Bravais lattices: primitive orthorhombic, base-centered orthorhombic, body-centered orthorhombic, and face-centered orthorhombic. For the base-centered orthorhombic lattice, the primitive cell has the shape of a right rhombic prism; it can be constructed because the two-dimensional cente… hate mickey mouse clubhouse

The construction of a simple powder diffractometer was first described by Hull in 1917 1 which was shortly after the discovery of X-rays by Wilhelm Conrad Röntgen in 1895 2. Diffractometer measures the angles at which X-rays get reflected and thus get the structural information they contains. WebThe body-centered cubic (bcc) lattice ( Figure 1.4b) can be obtained by adding a second lattice point at the center of each cubic cell of a simple cubic lattice. Thus, the unit cell of each bcc lattice can be considered as two interpenetrating simple cubic primitive lattices.
