SODIUM METABORATE TETRAHYDRATE Usage And Synthesis

Chemical Properties

white crystals or crystalline powder

Uses

It is used in textile finishing as a component of sizing, scouring compositions, adhesives, and detergents. It is also used in photography and agriculture.

Uses

Sodium Metaborate Tetrahydrate is used as a boron fertilizer for maize growth and uptake. it is also used as a source of boron in the production of Sodium borohydride which is a medium for hydrogen storage.

Production Methods

Sodium metaborate tetrahydrate may be made by cooling a solution containing borax and an amount of sodium hydroxide just in excess of the theoretical value.
