Borax Decahydrate – Chemical and Physical Properties
Sodium tetraborate, commonly known as borax, is an inorganic chemical compound with the formula Na₂B₄O₇·10H₂O. It occurs as colourless crystals and is the sodium salt of boric acid, soluble in water. Its physical and chemical properties, including its relatively low toxicity and ability to act as a flux, make it a valuable raw material in a wide range of industrial processes.
When heated, borax loses its water of crystallisation and, at temperatures of around 300–400°C, converts to its anhydrous form. It produces a green flame, a characteristic feature of many boron compounds. Borax occurs naturally as a mineral, including borax (tincal) and partially dehydrated forms such as tincalconite and kernite. With a Mohs hardness of 2–2.5, it is considered a relatively soft mineral.
Alternative names for borax include: borax decahydrate, sodium tetraborate decahydrate, disodium tetraborate decahydrate, sodium tetraborate, borax, E285.
Borax in Glass and Ceramics Production
Borax is an important raw material in glass and ceramics production. It is used as a flux, helping to lower the melting temperature of silica, facilitate glass forming, and improve adhesion and surface finish in ceramic products. Sodium tetraborate is also used in the production of glass wool.
Sodium Tetraborate in Metallurgy
In metallurgy, borax acts as a flux in soldering and welding processes, helping facilitate the melting and joining of metals. Its flame-retardant properties also make it useful in the production of fire-resistant materials.
Borax in Cleaning Product Manufacturing
Borax is a key raw material used in the production of sodium perborate (NaBO₃), which is widely used as a bleaching agent in detergents, particularly in Europe. In household applications, borax is also used as a cleaning and dehydrating agent.
Borax in Agriculture
Borax decahydrate is used as a component of fertilisers, supporting its application in agriculture. It serves as a source of boron, an essential micronutrient that supports plant growth in areas with boron-deficient soils. Its use can help improve crop yields and plant resistance to disease.
Borax – Pharmaceutical Applications
Sodium tetraborate decahydrate is also used in the pharmaceutical industry, where it may serve as a buffering agent and preservative in selected formulations.
