Caesium nitrate or cesium nitrate is a salt with the chemical formula CsNO3. An alkali metal nitrate, it is used in pyrotechnic compositions, as a colorant and an oxidizer, e.g. in decoys and illumination flares. The caesium emissions are chiefly due to two powerful spectral lines at 852.113 nm and 894.347 nm.Script error: No such module "Unsubst".

Caesium nitrate prisms are used in infrared spectroscopy, in x-ray phosphors, and in scintillation counters.[1] It is also used in making optical glasses and lenses.

As with other alkali metal nitrates, caesium nitrate decomposes on gentle heating to give caesium nitrite:

Caesium also forms two unusual acid nitrates, which can be described as CsNO3·HNO3 and CsNO3·2HNO3 (melting points 100 °C and 36–38 °C respectively).[2]
