Calculation of Number of Particles per Unit Cell of a Cubic Crystal System - Calculation of Number of Particles per Unit Cell of a Cubic Crystal System. Keeping the following points in mind we can calculate the number of atoms in a unit cell. An atom at the c..

Crystals along with suitable examples are listed in the table. System Axial distances Axial angles Examples Cubic a = b = c α = β = γ = 90° NaCl,KCl, Diamond, Cu, Ag Tetragonal a = b ≠ c α = β = γ = 90°..

Another type of microphone, widely used in public-address systems, depends for its action on the piezoelectric effect possessed by certain crystals, for example Rochelle salt. The term piezoelectric effect refers to the fact that when pressure is applied on the crystal..

Keeping the following points in mind we can calculate the number of atoms in a unit cell. * An atom at the corner is shared by eight unit cells. Hence an atom at the corner contributes 1/8 to the unit cell * An atom at the face is a shared by two unit cells Contribution of each atom..

Gout - Uric acid accumulates in the blood and deposits as crystals in joints, kidneys and cartilages. This is a hereditary diseas..

In addition to the particles at the corner of the cube, there is one present at the body centre position of the unit cell. Another type of unit cell, called end centered unit cell, is possible for orthorhombic and monoclinic crystal types. In an end centered unit cell, there are lattice ..

The smallest three-dimensional portion of a complete space lattice, which when repeated over and again in different directions produces the complete space lattice. The size and shape of a unit cell is determined by the lengths of the edges of the unit cell (a, b and c) and by the angles a , b a..

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and fuse. Fusion is the change of state from solid to liquid. This is generally referred to as melting. The temperature at which th..

Effect of Temperature and Pressure on States of Matter - When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperatur..

Ruby Laser - In 1960, T .H. Maiman constructed the first laser using a Ruby crystal. Ruby is a crystalline form of silica(Al 2 O 3 ) with a slight natural doping of chromium. It has the following advantages for being used as a laser. (i) It is a solid having suitably arranged energy level..
