Magnetic Properties of Solid
Magnetic Properties of Solid
Electrons are charged particles and it generates a magnetic field around itself. The magnetic field arises due to the spinning of...
Electrical Properties of Solid
Solids can be classified into three types on the basis of their conductivities.
Conductors:
The solids with conductivities ranging between 104 to 107 ohm–1m–1 are called...
Non-Stoichiometric Defects and Metal Deficiency Defect
Non-Stoichiometric Defects
A large number of non-stoichiometric inorganic solids are known which contain the constituent elements in non-stoichiometric ratio due to defects in their crystal...
Impurity Defects
Impurity Defects
If molten NaCl containing a little amount of SrCl2 is crystallized, some of the sites of Na+ ions are occupied by Sr2+ (Fig.).
Each...
Stoichiometric Defects
Stoichiometric Defects
These are the point defects that do not disturb the stoichiometry of the solid. They are also called intrinsic or thermodynamic defects.
Basically...
Imperfection in Solids
Single crystals are formed when the process of crystallization occurs at extremely slow rate. Even these crystals are not free of defects. The defects...
Packing efficiency in Body-centred cubic structures
Now consider the unit cell of body-centred cubic in which sphere ABCDEFGH are occupied at corner. And sphere c is placed at body-centre of...
Packing Efficiency
Packing efficiency is defined as the percentage of total space filled by the constituent particles in a crystal.
Packing efficiency in hcp and ccp structures:
Let...
Close Packed Structures
Close-Packed Structures
As we the constituent particles in solid are in form of a sphere. The spheres in solid are arranged in the different way...
Primitive unit cell
Primitive unit cell:
In a Primitive unit cell, atoms are present at the corner only. An atom is shared by 8 unit cell. Hence the...
