Borax pentahydrate

Borax , also known as sodium borate, sodium tetraborate. Borax pentahydrate, with a formula Na2B4O7.5H2O, is an important boron compound, a mineral, and a salt of boric acid.

Consists of white crystalline granules or powder. It is mildly alkaline in solution.

The advantages of this material vs. the decahydrate form lie in the lower transportation, handling and storage costs of a more concentrated product. 74.6 lb. of this material are equivalent to 100 lb. of decahydrate.

It is stable under ordinary conditions, free-flowing, and easily handled by air or mechanical conveying.

Borax has been around for years and was originally discovered in Tibet in dry lake beds. It was commonly used during the 19th century for laundry and other cleaning purposes.


Application of Borax pentahydrate

There are many applications for Borax. It is part of many detergents, cosmetics, and enamel glazes.

It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound, in the manufacture of fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, as a precursor for other boron compounds, and like boric acid, is effective as an insecticide.

Borax is very effective at keeping cockroaches, ants, water bugs and a few other household pests at bay. You just have to mix equal parts of borax with regular sugar. The sugar helps to draw the bugs in and the borax takes them away – permanently. Take care that you do not leave this out where pets or small children can reach it.
