Infobox references

Lanthanum(III) nitrate is a water soluble salt of lanthanum with the chemical formula La(NO3)3. The compound decomposes at 499°C to lanthanum oxide, nitric oxide and oxygen.[3]

## Uses

It is a starting chemical for the electrochemical synthesis of lanthanum permanganate and to make lanthanum oxysulfide. It is also a possible application for fluorescent display tubes.[1]

## Preparation

Lanthanum nitrate is prepared by reacting lanthanum oxide with nitric acid which creates lanthanum(III) nitrate and water.
