화재 위험	When heated to decomposition, it emits toxic fumes of cadmium. (Non-Specific -- Cadmium Compounds) Fire may produce irritating or poisonous gases. Runoff from fire control or dilution water may cause pollution. Oxides of cadmium react explosively with magnesium when heated. (EPA, 1998)Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
화재 가능성	Noncombustible
건강 유해성	The lethal inhalation dose of cadmium oxide in humans is 2,500 mg/m3 for a 1 minute exposure. Lethal exposure has been established at 50 mg (cadmium)/m3 for 1 hour for cadmium oxide dust and 1/2 hour for the fume. These concentrations may be inhaled without sufficient discomfort to warn worker of exposure. Inhalation may cause acute tracheobronchitis, pneumonitis, and pulmonary edema. Exposure can cause kidney and lung damage. Acute exposure by inhalation may cause death by anoxia. The lowest human toxic inhalation concentration is 8.630 mg/m3/5 hours for the fume. Persons with respiratory disorders should be excluded from contact with this material. (EPA, 1998)

제조 및 합성 방법

생산 방법

Cadmium oxide is manufactured commercially by distilling cadmium metal from graphite retort and allowing vapor to react with air.

제조 방법

Cadmium oxide is prepared by the reaction of cadmium vapor with oxygen. The metal is first melted in a steel retort and transported into a heated chamber where it is vaporized. The vapor is reacted with air, and the cadmium oxide formed is collected in a bag house. The particle size of the product depends on the ratio of air to cadmium vapor. The oxide may be further purified and particles of uniform size may be obtained by calcination at low red heat. Cadmium oxide also may be prepared by several other routes starting with various cadmium salts. The compound can be made by thermal decomposition of cadmium carbonate or cadmium hydroxide: CdCO3 → CdO + CO2 Cd(OH)2 → CdO + H2O Similar thermal decomposition of cadmium nitrate or sulfate would yield the oxide. he oxide. Cadmium oxide also may be made by high temperature oxidation of cadmium sulfide: 2CdS + 3O2 → 2CdO + 2SO2 Finely divided oxide may be obtained by pyrolysis of cadmium salts of carboxylic acids, such as cadmium formate or oxalate. (COOH)2Cd → CdO + H2O + 2CO (COO)2Cd → CdO + CO2 + CO
