使用
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.
一般的な説明
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.
空気と水の反応
Water soluble.
反応プロフィール
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].
危険性
Dangerous, may ignite organic materials on
contact.
健康ハザード
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.
火災危険
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.
安全性プロファイル
Moderately toxic by
ingestion and intraperitoneal routes.
Mutation data reported. When heated to
decomposition it emits toxic fumes of NOx.
See also CESIUM and NITRATES.
純化方法
It crystallises from water (0.6mL/g) between 100o and 0o. After 1 crystallisation of 99.9% grade salt, it had K, Na and Se at 0.8, 0.4 and 0.2 ppm respectively.
