This lamp is a white-light source with high color rendering index that sufficiently resembles sunlight to allow good color-reproduction with TV cameras. [67] About 80 kg of scandium is used in metal-halide lamps/light bulbs globally per year. [68]
In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide. [7] The particular mixture of metal halides influences the correlated color temperature and intensity (making the light more blue or red, for example). When started, the argon gas ...
The principal sources of rare-earth elements are the minerals bastnäsite (RCO 3 F, where R is a mixture of rare-earth elements), monazite (XPO 4, where X is a mixture of rare-earth elements and sometimes thorium), and loparite ((Ce,Na,Ca)(Ti,Nb)O 3), and the lateritic ion-adsorption clays.
This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
Sodium iodide and scandium iodide are commonly in use. These lamps can produce much better quality light without resorting to phosphors. If they use a starting electrode, there is always a thermal shorting switch to eliminate any electrical potential between the main electrode and the starting electrode once the lamp is lit.
A 20-pound chandelier that hung in the RMS Titanic has arrived at the Liberty Science Center in Jersey City, New Jersey, after spending decades sitting on the bottom of the Atlantic.
Scandium triiodide, also known as scandium iodide, is an inorganic compound with the formula ScI 3 and is classified as a lanthanide iodide. This salt is a yellowish powder. [ 1 ] It is used in metal halide lamps together with similar compounds, such as caesium iodide, because of their ability to maximize emission of UV and to prolong bulb life.
If you're tired of your stomach feeling like a distended balloon, you're not alone. In fact, it is pretty common. A study shows that almost 18% of people experience bloating at least once a week ...
