cad·mi·um

 (kăd′mē-əm)
n. Symbol Cd
A soft, bluish-white metallic element occurring primarily in zinc, copper, and lead ores, that is easily cut with a knife and is used in nickel-cadmium storage batteries, rustproof electroplating, nuclear reactor shields, solders, and in low-friction, fatigue-resistant alloys. Atomic number 48; atomic weight 112.41; melting point 321.1°C; boiling point 767°C; specific gravity 8.65; valence 2. See Periodic Table.

[Latin cadmīa, calamine (the ore of zinc from which cadmium was first extracted as an impurity) (from Greek kadmeia (gē), Theban (earth), from Kadmos, Cadmus; see Cadmus) + -ium.]

cad′mic (-mĭk) adj.

cadmium

(ˈkædmɪəm)
n
(Elements & Compounds) a malleable ductile toxic bluish-white metallic element that occurs in association with zinc ores. It is used in electroplating, alloys, and as a neutron absorber in the control of nuclear fission. Symbol: Cd; atomic no: 48; atomic wt: 112.411; valency: 2; relative density: 8.65; melting pt: 321.1°C; boiling pt: 767°C
[C19: from New Latin, from Latin cadmīa zinc ore, calamine, referring to the fact that both calamine and cadmium are found in the ore]

cad•mi•um

(ˈkæd mi əm)

n.
a white, ductile, divalent metallic element resembling tin, used in plating and in making certain alloys. Symbol: Cd; at. wt.: 112.41; at. no.: 48; sp. gr.: 8.6 at 20°C.
[< German Kadmium (1817) < Latin cadm(īa) zinc oxide]
cad′mic, adj.

cad·mi·um

(kăd′mē-əm)
Symbol Cd A rare, bluish-white metallic element that occurs mainly in small amounts in zinc ores. It is soft and easily cut with a knife. Cadmium is plated onto other metals and alloys to prevent corrosion, and it is used to make rechargeable batteries and nuclear reactors. Atomic number 48. See Periodic Table.

These pigments are generally less expensive than cadmiums and can actually drive down the cost of a formulation, suppliers say.
Most of the yellow, red organic pigments used as alternatives to the cadmiums have heat stabilities between 482 F and 572 F.
Organic pigments have lighter bulk densities than cadmiums, giving them greater surface area and requiring more carrier polymer to wet out and disperse the organic pigment For instance, an inorganic concentrate that had been formulated at 33:1 letdown ratio would have to be changed to a less economical 25:1 or 20:1 ratio.
With a growing number of states enacting legislation that would greatly reduce the allowable amounts of cadmium in packaging-and pigment, colorant and stabilizer suppliers developing more cadmium-free products-there may soon be little reason for processors to continue using cadmium-based additives.
Losing cadmiums would be like a composer losing the use of several keys," adds painter Robert Cottingham of Newtown, Conn.
These cadmium sulfide pigments were introduced only five years earlier, and artists put them to immediate and striking use.
Cadmium yellows have smeared painters' palettes ever since, with pigment processors now mixing the sulfides with touches of cadmium selenide to offer a sunset of golds, oranges and reds.
But the sun may indeed set on cadmium pigments in the United States if the Senate approves a proposed amendment to the 1989 Solid Waste Disposal Act.
A complete line of PVC heat stabilizers is available, including various combinations of barium, cadmium and zinc, custom designed for flexible PVC, including plastisols and organosols.
Company also offers dispersions of lead, barium, cadmium, tin and zinc-based compounds as concentrates or as pumpable pastes for automatic metering.
company's Vanstay PVC heat stabilizers constitute a line of custom formulated combinations of barium, cadmium, calcium, and zinc.
Noncadmium types, such as special zinc liquid systems, are available for applications where absence of cadmium is desired.
