Description
Sodium Metaborate is the sodium salt of Metaborate. Sodium metaborate is used in the manufacturing of borosilicate glasses. It is also a component of herbicides and antifreeze
1. It can also be used as an oil additive with anti-wear properties
2. Sodium metaborate electroreduction in the alkaline system can act as a novel desulphurization process of coal water slurry
3. It also has role in hydrolysis of sodium borohydride to minimize the water utilization
4. It can also act as a novel alkali in alkali/surfactant/polymer flooding
5. It is also useful in the thermo-chemical production of sodium borohydride
6, which is a safe and practical hydrogen storage material for on-board hydrogen production.

Chemical Properties
White lumps.Soluble in water. Noncombustible.
Uses
Herbicide. Also available commercially as
octahydrate and tetrahydrate.
Production Methods
Sodium metaborate is produced commercially by reacting boric acid with sodium carbonate or sodium hydroxide under controlled heating conditions. The process involves neutralisation and dehydration, yielding crystalline sodium metaborate hydrates or anhydrous forms depending on temperature and water content.
Definition
ChEBI: An inorganic sodium salt having metaborate as the counterion.
Agricultural Uses
Herbicide, Insecticide, Fungicide, Nematocid: Not listed for use in EU countries. Registered for use in the U.S
Agricultural Uses
Rasorite is one of the sources of borax which is produced
by re-crystallizing the ores. Borax (Na
