Na2MoO4·2H2O as a corrosion inhibitor is widely used in circulating water cooling system, engine coolant, metal working fluid, oil field drilling mud. Na2MoO4·2H2O is also used for anti-rust treatment of pigments, oils and metals, and is one of the main inorganic salt products in my country.
Na2MoO4·2H2O is usually a white rhombus crystal. Na2MoO4·2H2O loses 2 molecules of crystal water at 100 ° C, and is soluble in 1.7 parts of cold water and about 0.9 parts of boiling water. The pH of 5% sodium molybdate solution at 25°C is 9.0-10.0.
In industry, the raw material molybdenite (the main component MoS2) is oxidized and roasted to make crude molybdenum oxide, washed with nitric acid to remove impurities, then dissolved in sodium hydroxide aqueous solution, heated and concentrated to obtain sodium molybdate dihydrate Na2MoO4·2H2O.
Na2MoO4·2H2O is divided into four specifications according to different purposes, MSN-t, MSN-1, MSN-2 and MSN-3.

On January 30, 2023, molybdenum price rose by more than 20% in a single day, breaking a new 17-year high. Molybdenum is known as the "war metal", "steel warrior". Molybdenum is valued by more and more countries. China is the world's richest country in molybdenum resources, with reserves of 4.3 million tons, followed by the United States (2.7 million tons) and Chile (1.8 million tons), which acco...more
