tungsten ribbon lamp ne demek?

Volfram.
Simgesi W, atom numarası 74, atom kütlesi 184 g, e.n. 3400
Tungsten.
Rare element of the chromium group found in certain minerals, as wolfram and scheelite, and isolated as a heavy steel-gray metal which is very hard and infusible.
It has both acid and basic properties.
When alloyed in small quantities with steel, it greatly increases its hardness.
Symbol.
Specific gravity, 18.
This is a metal found in a number of minerals, but chiefly in wolframite In colloidal form it is used in the filaments of lamps As tungsten carbide it is used in a wide variety of cutting tools to give them long cutting life.
Tungsten is a gray-white heavy high-melting ductile hard polyvalent metallic element that resembles chromium and molybdenum in many of its properties and is used especially for electrical purposes and hardening alloys.
