Sodium dichromate is the inorganic compound with the formula Na2Cr2O7. Usually, however, the salt is handled as its dihydrate Na2Cr2O7·2H2O. Virtually all chromium ore is processed via conversion to sodium dichromate and virtually all compounds and materials based on chromium are prepared from this salt. In terms of reactivity and appearance, sodium dichromate and potassium dichromate are very similar. The sodium salt is, however, around twenty times more soluble in water than the potassium salt (49 g/L at 0 °C) and its equivalent weight is also lower, which is often desirable.[2]

This grade is intended for general applications like chemical synthesis, dyes, leather, fire extinguishers, water treatment, plastic molding, flue gas treatment & in the drilling industry, sodium bicarbonate is used to chemically treat drilling mud when it becomes contaminated with calcium ions from cement or lime.
It is NOT intended for applications, directly or indirectly, related to human consumption.
White powder or tiny crystals, inodorous and salty, easily soluble in water, insoluble in alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposed to moist air.
Natural soda is firstly dissolved into solution (Na2CO3) and filtrated. The clear solution is then fed to carbonizing tower ; accordingly, CO2 is compressed and bubbled up from the bottom of the tower, After carbonization, the slurry will be flowed from the bottom and separated. Dried to the finished product.
Usage: Used as food fermentation, detergent ingredient, carbondoxide foamer, pharmacy, leather, ore milling and metallurgy, detergent for wool, exiting usher and metal heat-treating, fiber and rubber industry, etc.
