Usage

Chemical Properties

white crystalline powder

Uses

Strontium hydroxide octahydrate is used in the sugar industry for its purification, oil and paint industry to improve its drying properties and as an active ingredient in depilatory hair removal products. It is also used as a raw material for manufacturing of other products of strontium salts.

Purification Methods

Crystallise the hydroxide from hot water (2.2mL/g) by cooling to 0o.
