It is also needed in making of binary (metal) alloy systems such as CuZn, Cu-Ni etc. Weldability is desired in the construction of laminated core of transformer. Appearance of any machine, equipment, or device provides elegancy and aesthetics to the product. 6 Operational Requirements of Electrical and Electronic Materials Electrical materials have to satisfy widely varying needs of diff erent operational parameters. These parameters are voltage, current, temperature, frequency, polarization, remanance, resistivity, emission etc.

A number of semiconducting compounds are available in oxide, halide and sulphide forms also. The n and p-types are used to make n-p junction for diode, n-p-n and p-n-p for transistor, etc. Semiconductors are generally hard and brittle, and possess negative coefficient of temperature resistance. In contrast with conductors whose conductivity increases with purification, the conductivity of semiconductors decreases with purification. Semiconductors are widely used as rectifiers, amplifiers, photocells etc.

The microstructural levels may further be classified as below. 1. 2. 3. 4.
