Borax Deca Pentahydrate (CAS 1303-96-4) is a sodium tetraborate decahydrate that appears as a white to gray, bluish or greenish white powder and serves as a boron source for borosilicate glass, micronutrient fertilizer and detergent builder applications. It acts as a powerful fluxing agent, lowering melting temperatures and improving chemical durability.
In the agriculture sector, it serves as a vital micronutrient fertilizer to correct boron deficiencies in soil. It promotes healthy plant reproduction and fruit development in commercial crops.
This chemical is also a key ingredient in detergent formulations, acting as a pH buffer and water softener. Its flame retardant properties make it valuable in construction material treatment.
