What is the color of cadmium oxide?
Cadmium oxide can be found as a colorless amorphous powder or as brown or red crystals.
What are the uses of cadmium?
Cadmium became an important metal in the production of nickel-cadmium (Ni-Cd) rechargeable batteries and as a sacrificial corrosion-protection coating for iron and steel. Common industrial uses for cadmium today are in batteries, alloys, coatings (electroplating), solar cells, plastic stabilizers, and pigments.
Where is cadmium most commonly found?
Sources of cadmium It is most often found in small quantities in zinc ores, such as sphalerite (ZnS). Cadmium mineral deposits are found in Colorado, Illinois, Missouri, Washington and Utah, as well as Bolivia, Guatemala, Hungary and Kazakhstan.
Why is cadmium bad for you?
Cadmium and its compounds are highly toxic and exposure to this metal is known to cause cancer and targets the body’s cardiovascular, renal, gastrointestinal, neurological, reproductive, and respiratory systems.
What are the signs of cadmium poisoning?
Cadmium is used for many items, including electroplating, storage batteries, vapor lamps and in some solders. The onset of symptoms may be delayed for two to four hours after exposure. Overexposure may cause fatigue, headaches, nausea, vomiting, abdominal cramps, diarrhea, and fever.
Where is cadmium oxide found?
Since cadmium compounds are often found in association with zinc ores, cadmium oxide is a common by-product of zinc refining. It is produced by burning elemental cadmium in air. Pyrolysis of other cadmium compounds, such as the nitrate or the carbonate, also affords this oxide.
What are the effects of cadmium?
Acute inhalation exposure (high levels over a short period of time) to cadmium can result in flu-like symptoms (chills, fever, and muscle pain) and can damage the lungs. Chronic exposure (low level over an extended period of time) can result in kidney, bone and lung disease.
What is an interesting fact about cadmium?
The bluish-white metal that is known as cadmium is malleable, ductile and can easily be cut with a knife. Due to its excellence as an electrical conductor, cadmium is often used in electroplating and in batteries. Also, cadmium and solutions of its compounds are toxic and must be handled carefully.
What kind of crystal structure does cadmium oxide have?
Cadmium oxide is an inorganic compound with the formula Cd O. It is one of the main precursors to other cadmium compounds. It crystallizes in a cubic rocksalt lattice like sodium chloride, with octahedral cation and anion centers.
How does CDO form on the surface of cadmium?
CdO is a basic oxide and is thus attacked by aqueous acids to give solutions of [Cd(H 2O) 6] 2+. forms. A thin coat of cadmium oxide forms on the surface of cadmium in moist air at room temperature.
How is cadmium oxide classified as a carcinogen?
/GENOTOXICITY/ Cadmium (Cd) is a toxic heavy metal that has been classified as a human carcinogen by the International Agency for Research on Cancer. The genotoxic effects of cadmium oxide (CdO) were investigated in cultured dog lymphocytes after a short-term oral CdO administration by the micronucleus (MN) test.
What is the vapor pressure of cadmium oxide?
Cadmium oxide is an n-type semiconductor with an energy gap of 222 kJ/mol (53 kcal/mol). Vapor pressure: 10 mm Hg at 1149 deg C; 40 mm Hg at 1257 deg C; 100 mm Hg at 1341 deg C; 400 mm Hg at 1484 deg C. Forms a variety of complexes, the most important of which is with cyanide ions.
