우라늄질산염 화학적 특성, 용도, 생산

• 화학적 성질

  Yellow, rhombic crystals. Soluble in water, alcohol, and ether.

• 물리적 성질

  The hexahydrate is a yellow crystalline solid; orthogonal crystals; density 2.81 g/cm³; hygroscopic; melts at 60°C; decomposes at 118°C; very soluble in water; soluble in alcohol and ether.

• 용도

  Uranyl nitrate is a yellow poisonous crystal made by dissolving uranic oxide in nitric acid. It is soluble in water, alcohol, and ether. First suggested by C. J. Burnett in 1855, a uranyl nitrate printing process was patented by Niépce de St. Victor in 1858. The paper was floated on a uranyl nitrate solution and dried in the dark. The paper was exposed under a negative in the sun until a faint image appeared. The image was developed to completion by floating the paper on a solution of silver nitrate or gold chloride followed by washing. A process patented in 1864 by Jacob Wothly called for adding uranyl nitrate and silver to collodion, which was then applied to paper. The Wothlytype was a printing-out process.
  Uranyl nitrate was used in printing-out emulsions and with potassium ferricyanide for toning prints and intensifying negatives. It was also used with silver nitrate for making uranium/ silver gaslight papers.

• 제조 방법

  Uranyl nitrate is obtained as an intermediate in recovering uranium from its minerals. The compound can be prepared by reacting triuranium octaoxide, U₃O₈, with nitric acid. It is separated and purified by extraction with ether.

• 위험도

  Strong oxidizer. Corrosive and irritating.

• Safety Profile

  Poison by inhalation. Moderately toxic by ingestion. Human mutation data reported. A corrosive irritant to skin, eyes, and mucous membranes. A radioactive material. A powerful explosive and oxibzer. Incompatible with cellulose. Ether solutions in sunlight may explode. When heated to decomposition it emits toxic fumes of NOx.
