- A halide is a binary
compound, of which one part is a halogen atom and the other part is an
element or radical that is less electronegative than the halogen, to
make a fluoride, chloride, bromide, iodide, or astatide compound.
- A halide ion is a
halogen atom bearing a negative charge. The halide anions are fluoride
(F−), chloride (Cl−), bromide (Br−), iodide (I−) and astatide (At−).
Such ions are present in all ionic halide salts.
- In organic chemistry
halides represent a functional group. Any organic compound that contains
a halogen atom can be considered a halide. Alkyl halides are organic
compounds of the type R-X, containing an alkyl group R covalently bonded
to a halogen X.
- Dihalides are
commonly used in the synthesis of cyclic alkanes.
- The typical halide
mineral is soft, can be transparent, is generally not very dense, has
good cleavage, and often has bright colors.
- Metal halides are
used in high-intensity discharge lamps called metal halide lamps, such
as those used in modern street lights. These are more energy-efficient
than mercury-vapor lamps, and have much better colour rendition than
orange high-pressure sodium lamps.
- Metal halide lamps
are also commonly used in greenhouses or in rainy climates to supplement
natural sunlight.
- Of all the lamps in
the high-intensity discharge (HID) family, the metal halide family of
lamps
has the brightest future. These lamps offer much higher
efficiency than mercury vapor lamps and better light quality than
either mercury or sodium lamps.
- Metal halide sales
have increased at an average rate of 15% each year.
- The number of prints
being produced on silver halide paper from film and digital imaging
devices will rise from 135 billion in 2000 to 142 billion in
2008.
- The growth of silver
halide based photography papers, silver usage for these products should
rise from 46.0 million troy ounces in 2000 to 60.1 million troy ounces
in 2008.
- Demand for X-ray
films, which represent the largest usage segment for silver halide, are
continuing to grow, despite
the emergence of sophisticated digital
X-ray technology. |
