Sodium Sulfide Market Size to Surpass USD 19.31 Billion by 2033
The global sodium sulfide market size is calculated at USD 11.83 billion in 2024 and is expected to surpass around USD 19.31 billion by 2033, expanding at a solid CAGR of 5.60% between 2024 and 2033.
The sodium sulfide market encompasses the production, distribution, and consumption of sodium sulfide, a chemical compound with the formula Na2S. Sodium sulfide is a versatile chemical utilized in a variety of sectors, including pulp and paper, the treatment of water, chemical photography, textiles, the leather trade, chemical manufacture, rubber chemicals, sulfur colors, ore flotation, oil recovery, dye synthesis, and detergent manufacturing. Its primary applications include the kraft process, treatment of water, chemical photography, fabrics, and leather processing.
It is also used in chemical manufacture for polymer chemicals, sulfur dyes, sulfonation and sulfomethylation, ore flotation, oil recovery, dye manufacturing, and detergent manufacturing. Sodium sulfide, also known as Na2S or Na2S·9H2O, is available in crystalline, flake, and fused forms. It is water soluble and creates highly alkaline solutions. When exposed to humid air, Na2S and its hydrates produce hydrogen sulfide, a poisonous, combustible, and corrosive gas that smells like rotten eggs.

Sodium Sulfide Market Coverage
Product Type Insights
The low ferric sodium sulfide segment is anticipated to witness rapid growth at a significant level during the projected period. Low ferric sodium sulfide is a yellowish, crystalline material used in the mining sector to process ores and metals. Its low iron concentration makes it ideal for situations where iron contamination is undesired. Its distinct qualities make it useful in a variety of industries, including dyes, medicine, leather and rubber manufacture, paper and clothing, treatment of wastewater, mineral extraction, and chemical manufacturing. It is used in the dye industry as a reducing agent and sulfur donor, resulting in brilliant hues. It is utilized in medicine to synthesize pharmaceuticals and conduct chemical processes. In the paper and textile industries, it is used as a bleaching and desulfurizing agent.
Application Insights
The textile segment dominated the sodium sulfide market in 2023. Sodium sulfide is an important reducing ingredient in textile dyeing processes, especially in the reduction of vat colors, sulfur dyeing, and indigo dyeing. It aids in the fixation of sulfur dyes to the textile substrate, making it easier to apply designs to textiles. Indigo dye synthesis is also aided by sodium sulfide, which reduces indigo to a water-soluble form that is then utilized in textile dyeing. Sodium sulfide can also be used to help dissolve colors and chemicals in textile printing pastes.
The water treatment segment is anticipated to witness rapid growth during the projected period. Sodium sulfide is an important oxygen scavenger in water treatment, eliminating dissolved oxygen from the water to prevent corrosion and other adverse reactions. It is used to cleanse and treat water for industrial and municipal usage, including removing pollutants, neutralizing pH, and eliminating toxins such as heavy metals. The water treatment market is expanding due to increasing environmental issues and regulatory restrictions. The efficacy of sodium sulfide in precipitating and eliminating contaminants from water makes it a vital element in water treatment systems, which drives demand in this market.
Recent Developments
In April 2024, Atsushi Sakuda and Akitoshi Hayashi, associate professors at Osaka Metropolitan University, discovered a technique for mass synthesis of sodium-containing sulfides. They employed sodium polysulfides as both the substrate and the flux, which promoted fusion. The researchers developed a solid sulfide electrolyte with the greatest recorded sodium ion conductivity and a glass electrolyte with strong reduction resistance. This mass synthesis is critical to the practical application of all-solid-state sodium batteries.
In April 2024, the study used metagenomics technology to investigate the co-metabolism of sulfur and nitrogen in compost using Na2S as an additive. The results showed that the experimental group had 19% and 34% greater nitrate and sulfate content, respectively, and blocked denitrification and sulfur reduction genes. The addition of Na2S increased compost quality by increasing the sulfate concentration.
In July 2023, Vishnu Chemicals Ltd completed experiments for Precipitated Barium Sulphate and Sodium Sulphide, which would be manufactured at a facility in Srikalahasti, Andhra Pradesh, with a capacity of 30,000 TPA and high whiteness, making it appropriate for pure white powder coatings.
