Sodium Sulfide Supplier
Sodium sulfide supplier is an important issue for supplying this product for end users to obtain a high quality product. It is a chemical compound with the formula Na2S and its hydrated form with the formula Na2S.9H2O, both of which are water-soluble salts that produce strong, colorless alkaline solutions. Although sodium sulfide is a yellow solid, its solution is colorless. Sodium sulfide occurs in crystalline, flaky, and fractured forms and, when exposed to air, releases hydrogen sulfide gas, which has a rotten egg odor. Sodium sulfide reacts with hydrogen peroxide to produce sodium sulfate.
Sodium Sulfide Production
In industry, sodium sulfide is obtained by reducing sodium sulfate with coal. These raw materials are abundant in nature. This reaction is carried out inside a furnace at a temperature of 1000 ° C. 0.5% sodium carbonate is added to this reaction. This substance acts both as a catalyst and as a neutralizing agent for any free acid.
The product obtained from the furnace is known as black ash, which is cooled, crushed, and washed several times with hot water. To prepare white crystals of sodium sulfide, 0.5% sodium cyanide is added to the liquid before crystallization.
In the laboratory, it is prepared by reacting sulfur with sodium in anhydrous ammonia solution or with sodium in dry tetrahydrofuran with a naphthalene catalyst. It is also obtained by reacting hydrogen sulfide and sodium hydroxide. In this method, sodium sulfide is produced in flakes.
Main Applications of Sodium Sulfide
Sodium Sulfide is a versatile industrial chemical, and its applications cover multiple sectors:
1. Leather Industry
One of the largest consumers of sodium sulfide is the leather tanning industry. It is used to remove hair and wool from hides during the unhairing process and helps soften the leather.
2. Pulp and Paper Production
In the paper manufacturing sector, sodium sulphide is used in the kraft process to break down lignin and separate cellulose fibers. It improves paper whiteness and production efficiency.
3. Mining and Ore Processing
In the mining industry, sodium sulfide is used as a flotation agent for non-ferrous ores like copper, molybdenum, and lead. It helps separate valuable minerals from waste rock.
4. Textile and Dye Industry
It serves as a reducing agent in textile dyeing, particularly for sulfur dyes, and plays an essential role in color fixation and dye solubility.
5. Chemical Manufacturing
Sodium sulphide acts as a precursor in producing other sulfur-containing chemicals such as sodium hydrosulfide (NaHS), sodium thiosulphate, and various pharmaceutical intermediates.
Global Market and Exporting Countries
The global market for sodium sulfide is growing due to industrial expansion in Asia, the Middle East, and Africa.
Major exporters of sodium sulphide include:
- China – the world’s largest producer and exporter of Sodium Sulfide or Na₂S flakes and liquid.
- India – a major exporter to African and Middle Eastern markets.
- Turkey and Iran – emerging suppliers with growing chemical production capacity.
- Germany and Russia – suppliers of high-purity industrial-grade sodium sulfide.
Growing demand from leather and mining industries in countries such as Kenya, South Africa, UAE, and Saudi Arabia has strengthened sodium sulphide trade across the Middle East and Africa.
Sodium Sulfide Market Price Trend
The price of sodium sulpfide fluctuates depending on:
- Purity (Na₂S 60% flakes or 30% liquid)
- Sulfur cost and energy prices
- Global freight rates and supply chain conditions
As of 2025, the average market price for Sodium Sulfide Flakes (Na₂S 60%) ranges between USD 350–600 per metric ton (CFR) depending on the region and order quantity. Prices remain stable in Asia and slightly higher in African import markets due to logistics costs.
