On hazardous silver compounds

Journal of Chemical Education, 1991
This review is intended to provide informatin so as to decrease likelihood that explosive silver compositions are formed by inadvertence: silver azide, silver fulminate, silver nitride, and silver ...

Compounds Formed in Silver Dental Amalgam

Journal of Dental Research, 1968
A high-resolution X-ray powder diffraction camera was used in the identification and crystallography of compounds in dental amalgam. The study included determination of the effects of the mercury-alloy ratio and of aging in clinical restorations. In all instances, γ silver-tin, y silver-mercury, and γ tin-mercury were found.

Characterization of Silver Sulfadiazine and Related Compounds

Journal of Pharmaceutical Sciences, 1974
Silver sulfonamides can be successfully recrystallized from strong ammonia solution. The spectral characterization of silver sulfadiazine, silver sulfamethazine, silver sulfanilamide, and silver sulfapyridine indicates that the silver sulfonamide formed on reaction of silver nitrate with the free sulfonamide or its sodium salt is correctly represented ...

Controlled filamentary growth of silver from silver compounds

Journal of Crystal Growth, 1972
Abstract Growth of filamentary silver was controlled using a solid-state-ionics technique. The controlled growth process was recorded on a 16 mm film, “High-speed growth of silver filaments”. The morphology of filaments was examined using a scanning electron microscope.

Superconductivity in Copper, Silver, and Gold Compounds

Chemistry – A European Journal, 2004
AbstractHigh‐temperature superconductivity exists in layered, square‐planar cuprates, but is almost absent in most other CuII compounds and in most AgII and AuII compounds. Valence state II is quite unusual in silver and gold and often disproportionates to valence states I and III (“negative‐U compounds”). The two‐electron difference in oxidation state

Preparation and Test In G Of Silver-Protein Compounds

Stain Technology, 1952
Silver derivatives of the protargol type were made from 13 different commercial peptones. The peptone samples were purified by precipitating with an ethanol concentration of 75%, reprecipitating once, and discarding any water-insoluble material. A 20–22% solution of the purified material in water, allcalinized with 2 ml.

Perfluoro organic compounds of silver

Journal of Fluorine Chemistry, 1980
Abstract Non fluorinated organo silver compounds are thermally unstable. In contrast fluorinated organo silver compounds are thermally more stable, the stability increasing with perfluoro aromatic counterparts rather than perfluoro aliphatic systems.

A New Type of Complex Silver Compounds with Tervalent Silver

Nature, 1943
IN course of a series of investigations1 in this laboratory on the complex compounds of biguanide and substituted biguanide with metallic elements, recently my pupil, K. Chakravorty, and I, have obtained a number of 4-co-ordinated silver ethylenebiguanide salts in which the central silver atom shows, rather strikingly, a primary valency of three. Their
