Product Short Description: Sodium Meta Silicate passivation chemical is suitable for Aluminum
Product Description:

Sodium Meta Silicate is special blend of chemical with corrosion inhibitor is suitable for Aluminum passivation. Chemical concept behind passivation is to provide light coat of a protective material, such as metal oxide, to create a shell against corrosion.

Product Application:

Pure aluminium naturally forms a tough resistant oxide, almost immediately that protects it from further oxidation in most environments. Aluminium alloys, however, offer little protection against corrosion. There are three main ways to passivate these alloys: alclading, chromate conversion coating and anodizing. Alclading is the process of metallurgically bonding a thin layer of pure aluminium to the aluminium alloy. Chromate conversion coating is a common way of passivating not only aluminium, but also zinc, cadmium, copper, silver, magnesium, and tin alloys. Anodizing forms a thick oxide coating. This finish is more robust than the other processes and also provides good electrical insulation, which the other two processes do not.


IN general practice prior to storing hydrogen peroxide in an aluminium container, the container can be passivated by rinsing it with a dilute solution of nitric acid and peroxide alternating with deionized water. The nitric acid and peroxide oxidizes and dissolves any impurities on the inner surface of the container, and the deionized water rinses away the acid and oxidized impurities.
