Hazard Information

General Description

CESIUM NITRATE(7789-18-6) is a colorless, glittering crystalline solid. CESIUM NITRATE(7789-18-6) is soluble in water. CESIUM NITRATE(7789-18-6) is a strong oxidizing material and may burst into flames on contact with organic materials.

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].

Air & Water Reactions

Water soluble.

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.

Chemical Properties

colourless crystals

Uses

A reagent used as a colorant and an oxidizer in pyrotechnic compositions

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.

Uses

preparation of other Cs salts.

Uses

Used in the synthesis of cesium nitratocuprate, Cs2[Cu(NO3)4], which crystallizes in a square-planar coordination around the Cu center.1

Flammability and Explosibility

Nonflammable

Purification Methods

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.
