What is sodium dichromate
Sodium dichromate is an inorganic compound with the chemical formula Na2Cr2O7. It is a bright orange-red crystalline solid that is highly soluble in water. It is an oxidizing agent and is often used as a laboratory reagent, as a chromium(VI) compound, and as a drying agent for paints and inks. It can also be used in the production of other chromium compounds, such as chromium(III) oxide, and as a catalyst in various chemical reactions.
Sodium dichromate is highly toxic and can cause irritation or burns to the skin and eyes, and inhaling the dust can cause respiratory problems. It should be handled with caution and protective measures should be taken when working with it.
How is sodium dichromate produced
Sodium dichromate is produced by the electrolysis of a solution of sodium chromate, which is itself produced by the dissolution of chromite ore in a solution of sodium hydroxide. The electrolysis process involves passing an electric current through the solution, which causes the sodium chromate to be oxidized to sodium dichromate.
The general process for producing sodium dichromate is as follows:
Chromite ore is mined and crushed to a fine powder.
The ore is then mixed with a solution of sodium hydroxide, which dissolves the chromium in the ore and forms a solution of sodium chromate.
The solution is filtered to remove impurities and then electrolysed using a diaphragm cell or a mercury cell.
During electrolysis, the sodium chromate is oxidized to sodium dichromate, while the hydrogen gas is produced at the cathode.
The sodium dichromate is then purified by crystallization and dried to form the final product.
Overall, the production of sodium dichromate involves several chemical reactions and requires specialized equipment and conditions. It is typically carried out on an industrial scale in order to meet the demand for the chemical.
What is sodium dichromate used for
Sodium dichromate is a highly versatile chemical that has a wide range of applications. Some of the main uses of sodium dichromate include:
As a laboratory reagent
Sodium dichromate is commonly used in chemical laboratories as a reagent in various types of reactions. It is particularly useful as an oxidizing agent, and is often used in the preparation of other chemicals, such as chromium(III) oxide.
As a chromium(VI) compound
Sodium dichromate is a source of chromium(VI) ions, which are highly reactive and can be used in a variety of chemical reactions. It is often used as a catalyst in the production of chemicals such as plastics, dyes, and pigments.
As a drying agent
Sodium dichromate is used as a drying agent in the production of paints, inks, and other coatings. It helps to remove water and other impurities from the mixture, which improves the final product’s stability and quality.
In water treatment
Sodium dichromate is used to remove iron and manganese from water, as well as to disinfect and purify water supplies.
In the leather industry
Sodium dichromate is used in the tanning process for leather. It helps to remove excess fat and protein from the skin, and also serves as a preservative to prevent the leather from deteriorating.
In the production of other chemicals
Sodium dichromate is used as a catalyst in the production of other chemicals, such as sodium chromate and sodium bichromate. These chemicals are used in a variety of applications, including the production of dyes, pigments, and ceramics.
Overall, sodium dichromate is an important chemical that has a wide range of applications in various industries. However, it is also highly toxic and should be handled with caution to avoid potential health risks.

BusinessAnalytiq provides a database of hundreds of market & price trend data, as well as online tools to set up benchmarks and leading indicators.
Where does the data come from?
- The source of the data are exclusively public non-confidential sources. We have no access to primary data
- This the index trend of the price trend of the "product category" in general, and not a single specification of the product in particular
- The data is a combination of contract and spot pricing
- Our algorithms are set up to eliminate significant product mix impact on the reported price
- We combine public publications, import/export records, trading prices, company announcements, magazine articles, tweets, and other sources of ad-hoc public information.
- The chart shows the our best approximation of the market trend based on our algorithm interpretation of the signals
- For most indexes we have multiple sources and we focus on using statistically-correlated sources
- As a function of our automation, it is likely that recent trends will be adjusted as we discover more information. So, for example, the price trend for February 2024 will be first calculated in February 2024 and adjusted in March, April and May 2024.
- We will update the data trend as more information becomes available, and this means that recent trends will always be adjusted as we get more data available
- The algorithm will regularly revise our understanding of market trends, and indicated market trends may change
- The data is presented in US$. The UOM of measure is shown in the Index list table
- Our automated software and we do our best to create an accurate representation of the trend
Where does the data NOT come from?
- We do not purchase data from any other source and republish it.
- We will not purchase data from any other source and republish it
- We do not extrapolate trends, even for the forecast. We look for other market signals and leading indicators
What data should our company use?
- If you are making decisions driving significant share of profit, we always recommend that you buy data from the companies who invest in direct primary market access such as ICIS, amongst many others
