Shares & Saves. Save. Xenon and halogen lights use a gas to help increase bulb effectiveness, but there are several key differences between them. Halogen lights are an older type of bulb that uses halogen gas primarily as a buffer and backup system, while xenon lights depend wholly on xenon gas to produce light.
Magnesium chloride is the name for the chemical compounds with the formulas MgCl 2 and its various hydrates MgCl 2 (H 2 O) x. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water.
Most magnesium comes from seawater which is composed of 0.13 percent of the element in the form of magnesium chloride. It can also be found in natural minerals such as dolomite and magnesite in the form of magnesium oxide.Magnesium can be produced through several different methods such as the electrolytic method, the thermal-reduction method or the most commonly used Pidgeon method.n this process, magnesium is collected from a condenser on the outside of a furnace. High priority magnesium can be attained from the condenser since vapor pressure of impurities that may be in the magnesium are low under the conditions of the tank. The largest producers of magnesium are China, Russia and Canada.
