The Difference Between Sodium Sulfide Yellow and Red Grade: Expert Supplying by Basekim

Sodium sulfide plays an essential role in multiple industries, including leather processing, mining, chemical manufacturing, water treatment, and pulp and paper production. Because different industries require different purity levels, sodium sulfide comes in two main grades: yellow and red. Although both serve important industrial purposes, they have distinct chemical compositions, physical properties, and applications. So, understanding these differences helps businesses make better sourcing decisions, improve efficiency, and reduce costs.

At Basekim, we specialize in supplying both yellow and red sodium sulfide grades. Since we work with leading global manufacturers, we provide consistent quality, competitive pricing, and reliable logistics solutions. Additionally, our expert team helps businesses choose the right grade based on their specific needs, ensuring maximum efficiency and performance.

Key Differences Between Sodium Sulfide Yellow and Red Grade

Because sodium sulfide yellow and red grades vary in composition, purity, and industrial applications, businesses must carefully assess their requirements before making a purchase. Selecting the right grade enhances productivity, cost savings, and operational stability.

1. Chemical Composition and Purity Levels

Since chemical composition directly affects industrial performance, sodium sulfide yellow and red grades contain different levels of purity.

• Sodium Sulfide Yellow Grade: This grade offers higher purity, typically containing 60% to 62% Na₂S content. Because it undergoes a more refined production process, it contains fewer impurities, making it ideal for applications that demand greater chemical stability and consistency. Therefore, industries that require high precision rely on this grade for optimal results.
• Sodium Sulfide Red Grade: In contrast, the red grade contains 50% to 55% Na₂S content. Since it has a higher percentage of iron impurities, it appears reddish-brown. Although it is slightly less pure than the yellow grade, it still performs well in many industrial processes. However, businesses should consider its impurity levels before selecting it for sensitive applications.

2. Color and Physical Properties

Because different refining techniques influence the final product, sodium sulfide grades exhibit distinct colors.

• Yellow Sodium Sulfide has a bright yellow to orange color, which indicates low impurity levels and high chemical purity. Due to its refined composition, it maintains a more stable chemical structure, ensuring higher efficiency in industrial processes.
• Red Sodium Sulfide appears reddish-brown, mainly due to iron compound impurities. While its chemical properties remain strong, its stability slightly differs from the yellow grade. Since its color reflects its impurity levels, industries must carefully determine whether it meets their requirements.

3. Industrial Applications and Best Uses

Since every industry requires specific chemical properties, selecting the right sodium sulfide grade is crucial. By choosing the appropriate grade, businesses can enhance efficiency, reduce chemical waste, and lower costs.

Best Uses for Sodium Sulfide Yellow Grade

• Leather Processing: Because yellow grade sodium sulfide has high purity, it effectively removes hair and fats from animal hides, ensuring better leather quality. Therefore, it remains the preferred choice for tanneries worldwide.
• Pulp and Paper Production: Since it improves the chemical pulping process, it helps manufacturers achieve higher-quality paper products. Additionally, it contributes to a more efficient production cycle.
• Water Treatment: Because it reacts efficiently with heavy metals, it enhances wastewater purification and industrial water treatment. Thus, it plays a vital role in ensuring environmental safety.
• Textile and Dye Industry: Since it serves as a reducing agent, it plays a crucial role in fabric dyeing and color stabilization. As a result, it ensures uniform and long-lasting textile coloration.

Best Uses for Sodium Sulfide Red Grade

• Mining and Ore Processing: Because red grade sodium sulfide helps separate valuable minerals, it plays a key role in metal extraction. Consequently, it remains essential for mineral processing industries.
• Chemical Manufacturing: Since it functions as a strong reducing agent, it is widely used in various industrial chemical reactions. Furthermore, its cost-effectiveness makes it a preferred choice for large-scale production.
• Wastewater Treatment: Although it contains iron impurities, it still effectively removes contaminants and neutralizes pollutants. Therefore, industries seeking a more affordable treatment option often consider this grade.
