Uses
Source of uranium dioxide, extraction of uranium
into nonaqueous solvents. 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.
