W. H. Miller in 1839 represented the planes of a crystal by a set of three integers h, k and l, called the Miller indices. To obtained the Miller indices for any crystal plane, the ratios of the intercepts made by the unit plane to those made by the given plane or its parallel plane…
Theoretical Density :- Knowing the unit cell dimensions, the theoretical density d of a cubic crystal can be calculated from the equation d = Z M / N V where Z is the number of atoms in the unit cell, M is the molar mass, V is the volume of the unit cell and N…
Crystal Lattice :- If the three dimensional arrangement of constituent particles like atoms, molecules or ions in a crystal is represented diagrammatically, in which each particle is depicted as a point, the arrangement is called crystal lattice. In 1848, Auguste Bravais showed with the help of geometrical calculations that there are 14 possible three dimensional…
Solid state :- Types of Solid :- On the basis of the nature of order present in the arrangement of their constituent particles, Solid or solid state can be classified as Crystalline and Amorphous. Crystalline Solid :- A crystalline solid state usually consists of a large number of small crystals, each of them having a…
