• 用途

  無機カドミウム化合物の製造中間体、研究用試薬

• 化学的特性

  Cadmium sulfate is a white to colorless, odorless, crystalline substance.

• 物理的性質

  Colorless orthogonal crystal; the hydrates have monoclinic crystal system; density 4.69 g/cm³ (density of mono-, and octahydrates is 3.79 and 3.08 g/cm³, respectively); melts at 1,000°C (octahydrate decomposes at 40°C); soluble in water, insoluble in ethanol.

• 使用

  Cadmium sulfate (CdS), also called “orange cadmium,” is used to produce phosphors and fluorescent screens. It is also used as a pigment in inks and paints, to color ceramics glazes, in the manufacture of transistors in electronics, photovoltaic cells, and solar cells, and in fireworks.

• 製造方法

  Cadmium sulfate is prepared by the reaction of cadmium metal or its oxide or hydroxide with dilute sulfuric acid:
  CdO + H₂SO₄ → CdSO₄+ H₂
  CdO + H₂SO₄ → CdSO₄ + H₂O
  Cd(OH)₂ + H₂SO₄ → CdSO₄+ 2H₂O.

• 一般的な説明

  Odorless white solid. Sinks and mixes slowly with water.

• 空気と水の反応

  Water soluble.

• 反応プロフィール

  Cadmium sulfate acts as a weakly acidic inorganic salt, which is soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

• 危険性

  A confirmed carcinogen.

• 健康ハザード

  Inhalation may cause dryness of throat, coughing, constriction in chest, and headache. Ingestion may cause salivation, vomiting, abdominal pains, or diarrhea. Contact with eyes causes irritation.

• 火災危険

  Special Hazards of Combustion Products: Toxic cadmium oxide fume may form in fires.

• 安全性プロファイル

  Confirmed human carcinogen with experimental carcinogenic data. Poison by ingestion, subcutaneous, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Mutation data reported. See also CADMIUM COMPOUNDS and SULFATES. When heated to decomposition it emits very toxic fumes of Cd and SOx.

• 職業ばく露

  It is used in pigments, electroplating; as a fungicide; and in synthetic and analytical chemistry. Also used in fluorescent screens; as an electrolyte. Incompatibilities: Acts as a weak inorganic acid; neutralizes bases. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, sulfur, selenium, tellurium, zinc

• 輸送方法

  UN2570 Cadmium compounds, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

• 予防処置

  Cadmium compounds cause more health disorders to occupational workers and persons with pre-existing skin disorders, eye problems, blood disorders, prostate problems, or impaired liver, kidney, or respiratory function. These workers are more susceptible to the effects of cadmium salts. On contact with cadmium, exposed workers should wash the skin and eyes immediately with plenty of water
