It is a radium salt of hydrogen chloride. It was the first radium compound isolated in a pure state. Marie Curie and André-Louis Debierne used it in their original separation of radium from barium. The first preparation of radium metal was by the electrolysis of a solution of this salt using a mercury cathode. [2] [1]: 3
Radium carbonate is a chemical compound of radium, carbon, and oxygen, having the chemical formula Ra C O 3. It is the radium salt of carbonic acid. It contains radium cations (Ra 2+) and carbonate anions (CO 2− 3). This salt is a highly radioactive, amorphous, [4] white powder that has potential applications in medicine.
Tho-Radia, a cream containing radium bromide, notable for its iconic advertising using the name of Dr. Alfred Curie, who shared the surname of Pierre and Marie Curie but had no connection to them. Radithor, a solution of radium salts, which was claimed by its developer William J. A. Bailey to have curative properties.
Additionally, radium phosphate, radium oxalate, and radium sulfite are probably also insoluble, as they coprecipitate with the corresponding insoluble barium salts. [5] The great insolubility of radium sulfate (at 20 °C, only 2.1 mg will dissolve in 1 kg of water) means that it is one of the less biologically dangerous radium compounds. [6]
Radium bromide is the bromide salt of radium, with the formula RaBr 2. It is produced during the process of separating radium from uranium ore . This inorganic compound was discovered by Pierre and Marie Curie in 1898, and the discovery sparked a huge interest in radiochemistry and radiotherapy .
In addition to its medical usage, radium was used in the 1920s and 1930s for making watch, clock and aircraft dials. Because it takes approximately three metric tons of uranium to extract 1 gram of radium, prodigious quantities of uranium were mined to sustain this new industry. The uranium ore itself was considered a waste product and taking ...
Radium sulfate (or radium sulphate) is an inorganic compound with the formula RaSO 4 and an average molecular mass of 322.088 g/mol. [3] This white salt is the least soluble of all known sulfate salts. [4] It was formerly used in radiotherapy and smoke detectors, but this has been phased out in favor of less hazardous alternatives.
Radium chlorate is an inorganic compound with formula Ra(ClO 3) 2. [1] While pure radium chlorate has never been prepared, [1] it is known to form coprecipitates using barium chlorate as a carrier. [2] These react with excess ammoniacal ammonium carbonate to form a mixed precipitate of radium carbonate with barium carbonate. [2]
