7789-18-6 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.

Chemical Properties
colourless crystals
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.

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.
Check Digit Verification of cas no
The CAS Registry Mumber 7789-18-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7789-18:
(6*7)+(5*7)+(4*8)+(3*9)+(2*1)+(1*8)=146
146 % 10 = 6
So 7789-18-6 is a valid CAS Registry Number.

Phase formation along the PO34/Zr = 1.5 Section of the ZrO(NO3)2-H3PO4-CsF-H 2O system
Godneva,Motov,Kuznetsov,Shchur
, p. 492 - 498 (2012)
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.
