Sodium dichromate (sodium red vitriol) has a wide range of applications. Zhenhua Co., Ltd. is a leading enterprise in my country.

Sodium dichromate, also known as sodium vitriol, has a chemical formula of Na2Cr2O7 and is an inorganic compound. Sodium dichromate appears as orange-red crystalline powder, soluble in water but insoluble in ethanol. Sodium dichromate has the characteristics of hygroscopicity, oxidation, deliquescence, and corrosiveness. It is widely used in chemical industry, synthetic fibers, medicine, electroplating, printing and dyeing, glass and other fields.

Sodium dichromate is a subdivided product of dichromate, which is the chromium salt with the widest application range. With technological advancement, my country’s dichromate production capacity and output continue to grow, and the industry’s development speed has accelerated. Against this background, the market space for sodium dichromate will continue to expand.

​​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ However, in recent years, with the increasingly strong downstream demand, my country’s industry as a whole has shown a situation of short supply, and the scale of product imports has increased. According to statistics from the General Administration of Customs of China, my country’s sodium dichromate import volume will reach 6,687.4 tons in 2022, and the import value will reach US$11,000. Turkey, South Africa, the United States, India, Germany and other countries are the main importers of sodium dichromate in my country.

According to the “2023-2028 China Sodium Dichromate (Sodium Red Alum) Industry Market In-depth Research and Development Prospects Forecast Report》shows that sodium dichromate is widely used in chemical industry, synthetic fibers, medicine, electroplating, printing and dyeing, glass, etc. In the field of chemical industry, sodium dichromate is an important chemical raw material, which can be used to manufacture potassium dichromate, ammonium dichromate, chromium oxide green, chromic anhydride and other chromium salt products; in the field of synthetic fibers, sodium dichromate can be used to make synthetic fibers. Fiber oxidant; in the pharmaceutical field, sodium dichromate can be used to produce pharmaceutical raw materials such as revanol, benzocaine, folic acid, and dapsone; in the printing and dyeing field, sodium dichromate can be used to produce vat dyes, aniline dyes, etc. .

​ ​ ​ ​ Major global manufacturers of sodium dichromate include Turkey’s Jinshan Group, American Hemmings Company, Germany’s Lanxess Group, etc. Jinshan Group is the world’s largest chromium salt manufacturer, its products are exported to many countries and regions around the world, and it is my country’s main supplier of sodium dichromate.

In terms of the local market, my country’s sodium dichromate industry is highly concentrated, and Zhenhua Co., Ltd., as the leading company, occupies nearly 50% of the market share. The sodium dichromate independently produced by Zhenhua Co., Ltd. is mainly used to synthesize vitamin K3, a nutritional feed additive. Its technical level and product quality have reached a leading position in the world. According to the semi-annual report of Zhenhua Co., Ltd., the company achieved revenue of 1.71 billion yuan in the first half of 2023.

Industry analysts said that sodium dichromate is hygroscopic and oxidizing, and is widely used in many fields. In the future, with the gradual release of market demand, the development trend of my country’s sodium dichromate industry will continue to improve. At present, due to factors such as inventory shortages, my country’s import dependence on sodium dichromate has increased. In the future, with technological advancement, my country’s sodium dichromate production capacity will be further expanded and output will continue to grow.
