As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide)

The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
A Power Diode is used when a large current is involved which needs a larger junction to dissipate the heat generated. An advantage of using the Power Diode is it is able to withstand high voltage without being damaged. A disadvantage about the Power Diode is that being a large junction it is unable to stand high frequency applications.
The power dissipated by a diode is P = Vf x I watts, where Vf is the forward voltage drop on diode (typically 0.5 volts for silicon diode) and I is the current.
It is generally accepted to be approximately .7 volts.
The type of diode used to convert alternating current in to direct current is the power diode.
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
It will be dissipating more power than a small signal diode.
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.

It is designed to operate while dissipating higher power than average types of diodes can.
Not sure of your context. A diode is a diode. One artificial distinction might be that an electric diode refers to a diode used in a higher power application with more current where an electronic diode might be found on a circuit board as part of an electronic lower power application.

Power diodes are made primarily of silicon, though small quantities of other materials, such as boron, gallium arsenide, germanium or phosphorous are also used.
It depends on how the diode is damaged. There are generally two cases. One, the diode is shorted, and conducts with a low impedance in both directions. The other, the diode is open, and does not conduct, having a high impedance, in both directions. The effect depends on the particular circuit. In a power supply, a shorted diode will often blow the fuse, while an open diode will result in no output, or in high ripple voltage output. Is it possible that diode has normal voltage output but wrong current,meaning low mA?
The diode laser module is more effective at reducing power consumption in machines because it has the lowest possible pump photon energy. It is made by pumping a solid gain medium such as a ruby.
