First Uses of Tungsten

The initial application of tungsten was in the production of incandescent lamp filaments. Despite the rise of energy-efficient LED lamps, tungsten remains crucial in the lighting industry due to its exceptional high-temperature strength—the best among the common refractory metals: Molybdenum, Tantalum, Tungsten, and Niobium.

Certain specialty incandescent lamps, such as halogen lamps, continue to use tungsten filaments. Additionally, tungsten electrodes are employed in high-intensity arc lamps.

However, lamp filaments are not composed of pure tungsten. Instead, they are made from a "doped" alloy containing micron-sized potassium bubbles, which stabilize the grain structure and create a highly creep-resistant material. Previously, arc lamp electrodes were made from tungsten doped with thoria (thorium oxide), but the resulting radon exposure concerns have ceased its use worldwide.

Alternative materials, such as potassium-doped tungsten and tungsten doped with lanthanum oxide or combinations of lanthanum and zirconium oxides, have since been implemented. Though these materials are not as effective in promoting easy arc formation and stable arcs in lamps, they pose significantly fewer environmental and health risks.
