Properties

Appearance: Lanthanum Chloride powder is usually a white crystalline powder.

Density: Relatively high density, about 3.84 g/cm³.

Melting point: melting point is 858℃ (some data show 860℃).

Boiling point: Boiling point is about 1000℃.

Solubility: Lanthanum chloride powder is easily soluble in water and decomposes easily in hot water; it is also easily soluble in ethanol and pyridine, but insoluble in ether and benzene.

Hygroscopicity: Lanthanum chloride powder has strong hygroscopicity, easily absorbing water in the air and deliquescing.

Thermal stability: easy to decompose and generate chlorine oxides when heated in air.

Hydrolysis: slightly hydrolysed after dissolved in water, making the aqueous solution acidic.

Reactivity: it can react with many kinds of substances, for example, it reacts with hydrogen sulphide to generate lanthanum sulphide under heating condition, and reacts with alkali to generate hydroxide or chlorine oxide precipitate.
