duced. Besides
tungsten filament bulb
, it is also used in scanning electron microscopy.

Properties of tungsten filament:
Tungsten filament is characterized by high melting point, low vapor pressure. In addition, it is quite sturdy and provides stable and uniform electron emission, therefore, tungsten filament is suited for manufacturing lamps. Its surface is smooth and has compact crystal structure.
