Purity 99.9% Disodium Tetraborate Borax Decahydrate, CAS 1303-96-4 White Granular Borax 10 Mol for Corrosion Inhibition
1. Borax Decahydrate Introduction
Borax decahydrate, also known as sodium borate decahydrate or simply borax, is a naturally occurring mineral compound that is often used in various household and industrial applications. It is composed of sodium, boron, oxygen, and water molecules.Borax decahydrate is a chemical substance with the molecular formula Na2B4O7 · 10H2O. It is a semi transparent colorless crystal or crystalline white powder. Borax decahydrate has no odor and a salty taste. When heated to 350-400 ℃, borax decahydrate will lose all its crystalline water and become anhydrous borax. Borax decahydrate is soluble in water and also in glycerol, but insoluble in alcohol. Its aqueous solution is weakly alkaline and appears colorless glassy when melted.

3. Borax Decahydrate for Corrosion Inhibition
Borax decahydrate is incorporated in many aqueous systems requiring corrosion inhibition, including automotive and engine coolant formulations, and various water treatment chemicals. Aqueous solutions of borax decahydrate have replaced chromates in railroad and other diesel engine coolants. It also protects ferrous metals against oxidation. Borax decahydrate’s high solubility in ethylene glycol makes it especially useful in car antifreeze formulations. It neutralizes acidic residue resulting from the decomposition of ethylene glycol and minimizes the rate of oxidation at the surface of the metal.
Usage of borax decahydrate in corrosion inhibition:
Passivation: Borax can facilitate the passivation of metal surfaces, forming a protective oxide layer that acts as a barrier against corrosive agents. This passive film helps to inhibit the electrochemical reactions that lead to corrosion.
PH Buffering: Borax can help to maintain a stable pH environment around metal surfaces, which is crucial for preventing corrosion. By acting as a pH buffer, borax can mitigate the acidic or alkaline conditions that promote corrosion.
Complex Formation: Borax has the ability to form complexes with metal ions, which can reduce the activity of these ions and inhibit corrosion processes. These complexes can help to stabilize metal surfaces and minimize their susceptibility to corrosion.
Inhibitor Synergy: Borax is often used in combination with other corrosion inhibitors to enhance their effectiveness. The synergistic effects of borax with other inhibitors can provide a more comprehensive and long-lasting protection against corrosion.
