argon gas preserve the filament from oxidation from high temperature
By replacing oxygen in the bulbs, argon can prevent the corrosion by oxidation of the filament.
Argon
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
fills light bulbs and incandescent lamps to protect the filament
used as filling for fluorescent lamps, electric light bulbs, incandescent lamps and for vacuum tube.
Different kinds of light bulbs used different gasses. The incandescent bulb uses no gas - it uses a vacuum. Other kinds of bulbs may use nitrogen, argon, neon, or krypton.
Incandescent bulbs use 75-100 watts. Fluorescent bulbs use around 10 watts. LED bulbs usually use 1 watt.
Argon and nitrogen are the two main gases used in bulbs today.See related links below
I am replacing all of my incandescent light bulbs today.
Most incandescent bulbs contain mostly nitrogen, which is sufficiently nonreactive and considerably cheaper than argon. A vacuole is part of a cell.
Argon is an element that is a gas at room temperature. It can be found in incandescent light bulbs because it is inert.
Argon is often used when an inert atmosphere is needed. It is used in this way to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.
