| | Cesium nitrate Usage And Synthesis |
| Description | Cesium nitrate is a strong oxidizing material and may burst into flames when it is in contact with organic materials.
Cesium nitrate is used as a colorant and oxidizer in the pyrotechnic industry, in petroleum cracking, in scintillation counters, and in x-ray phosphors. It is used as a promoter in heterogeneous catalysts.

| | Chemical Properties | colourless crystals | | Uses | Used in the synthesis of cesium nitratocuprate, Cs2[Cu(NO3)4], which crystallizes in a square-planar coordination around the Cu center.1 | | Uses | A reagent used as a colorant and an oxidizer in pyrotechnic compositions | | Uses | preparation of other Cs salts. | | Uses | Cesium nitrate prisms are used in infrared spectroscopy, x-ray phosphors and scintillation counters. It is a precursor material for the synthesis of cesium nitratocuprate and cesium salts. Cesium nitrate doped on carbon-based ruthenium catalyst plays an important role in synthesis of ammonia. | | General Description | Cesium nitrate is a colorless, glittering crystalline solid. Cesium nitrate is soluble in water. Cesium nitrate is a strong oxidizing material and may burst into flames on contact with organic materials. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | Mixtures of metal/nonmetal nitrates with alkyl esters may explode owing to the formation of alkyl nitrates. Mixtures a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. | | Hazard | Dangerous, may ignite organic materials on
contact.
| | Health Hazard | Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. | | Fire Hazard | These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard. | | Flammability and Explosibility | Nonflammable | | Safety Profile | Moderately toxic by
ingestion and intraperitoneal routes.
Mutation data reported. When heated to
decomposition it emits toxic fumes of NOx.
