Usage

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.

Uses

Different sources of media describe the Uses of 7789-18-6 differently. You can refer to the following data:
1. Used in the synthesis of cesium nitratocuprate, Cs2[Cu(NO3)4], which crystallizes in a square-planar coordination around the Cu center.1
2. A reagent used as a colorant and an oxidizer in pyrotechnic compositions
3. preparation of other Cs salts.
4. 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.

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. See also CESIUM and NITRATES.

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.

Phase formation along the PO34/Zr = 1.5 Section of the ZrO(NO3)2-H3PO4-CsF-H 2O system

The phase formation in the system ZrO(NO3)2 H 3PO4 CsF H2O was studied along the section at the molar ratios PO^/Zr = 1.5 and CsF/Zr = 2-5 at a ZrO2 concentration in the initial solution of 2-5 wt %. New fluorophosphate zirconates, CsH2Zr2F2(PO4)3 · 1.5H2O and two modifications of CsZrF2PO4 · 0.5H 2O, were isolated, and the known phosphate zirconate CsZr 2(PO4)3 was obtained for the first time by calcining acidic fluorophosphate zirconate.
