Sodium Sulfide (Caustic Soda Flakes)

Sodium sulfide, also known as soda lye flakes or sodium sulfhydrate in its flake form, is an inorganic compound with the chemical formula Na2S. It appears as colorless crystals or yellow-to-reddish flakes and is highly soluble in water. It has a strong reducing property and emits a characteristic rotten-egg odor due to hydrogen sulfide (H2S) gas release when exposed to air or acids.

Sodium sulfide is classified as a hazardous chemical and is widely used in industries including dyes, leather processing, paper making, textile dyeing, metallurgy, and chemical synthesis.As a key member of Inorganic Chemical Products, Sodium Sulfide Flakes is widely used as a high-performance reducing agent in multiple heavy industries. It is commonly supplied in industrial grades such as Na2S Industrial Grade, ensuring stable chemical performance and reliable processing efficiency across large-scale production environments.

Product Overview

Sodium sulfide (Na2S) in flake form is one of the most important inorganic chemicals used in industrial applications worldwide. It is a powerful reducing agent and source of sulfide ions, making it indispensable in processes ranging from leather dehairing to mineral flotation. The product is manufactured in multiple purity grades — typically 60%— to meet the demands of different industries.

What is Sodium Sulfide Flakes?

Sodium Sulfide Flakes (Na₂S) is an inorganic sulfur compound commonly available in yellow to red flaky form. It is highly soluble in water and acts as a strong reducing agent in industrial chemical reactions.

Sodium Sulfide Flakes is typically produced in different purity levels, with Sodium Sulfide 60% being one of the most widely used industrial grades due to its balance of reactivity and cost efficiency.

Key chemical identification:

● CAS No.: 1313-82-2

● Molecular Formula: Na₂S

● Appearance: Yellow / Red flakes

● Grade: Na2S Industrial Grade / Technical Grade

In industrial supply chains, Sodium Sulfide Flakes Supplier selection is critical because product purity directly affects downstream process efficiency and safety.

Because of its hazardous nature (corrosive, toxic by H2S release), handling requires proper personal protective equipment and compliance with international dangerous goods regulations. We hold the required dual-use export permits for compliant international shipments to markets across Southeast Asia, Africa, and South America.
