Rubidium nitrate

Rubidium nitrate is an inorganic compound with the formula RbNO3.

This alkali metal nitrate salt is white and highly soluble in water.

[1] Like caesium nitrate, it is used in infrared radiation optics, in pyrotechnic compositions as a pyrotechnic colorant and as an oxidizer, e.g. in decoys and illumination flares although it is rarely used in fireworks to produce a red-violet colour.

It is also used as a raw material for preparation of other rubidium compounds and rubidium metal, for manufacture of catalysts and in scintillation counters.

RbNO3 can be prepared either by dissolving rubidium metal, its hydroxide or carbonate in nitric acid.

Unit cell
NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazard OX: Oxidizer. E.g. potassium perchlorate
