Barium Sulfide (BaS), identified by CAS 21109-95-5, is an inorganic compound with a fascinating chemistry that underpins its diverse industrial applications. As a leading Barium Sulfide manufacturer and supplier in China, we are committed to providing materials with well-understood properties and reliable synthesis routes. This article explores the fundamental chemistry of Barium Sulfide, its key properties, and the typical methods employed for its industrial production, emphasizing the importance of quality when you buy this compound.

Chemically, Barium Sulfide is an ionic compound formed between the alkaline earth metal barium (Ba²⁺) and the sulfide ion (S²⁻). It crystallizes in the rock salt (NaCl) structure, where barium and sulfur ions are octahedrally coordinated. Its molecular weight is approximately 169.39 g/mol. One of its most notable properties is its appearance: typically a pale gray to yellow powder, although it can be obtained in purer, whiter forms. Barium Sulfide is known to react with water, although its solubility is moderate at lower temperatures, increasing significantly with temperature. Crucially, it reacts with acids to liberate toxic hydrogen sulfide gas (H₂S), a property utilized in analytical chemistry but also necessitating careful handling and storage. As a chemical supplier, we ensure our product’s stability and reactivity are consistent.

The industrial synthesis of Barium Sulfide primarily relies on the carbothermic reduction of barium sulfate (BaSO₄), a process that has historical roots dating back to the discovery of Bolognian stone. In this method, barium sulfate, often sourced from the mineral barite, is heated at high temperatures with a reducing agent, typically carbon (coke or charcoal). The reaction can be simplified as: BaSO₄ + 2C → BaS + 2CO₂. This process requires carefully controlled conditions to achieve good yields and purity. Modern manufacturing techniques employed by companies like ours focus on optimizing these parameters to ensure a consistent and high-quality output. When you buy Barium Sulfide, you are essentially purchasing the result of this carefully managed chemical transformation.

The properties of Barium Sulfide dictate its suitability for various applications. Its role as a precursor is significant; it readily converts into other important barium compounds such as barium carbonate (BaCO₃), barium chloride (BaCl₂), and barium oxide (BaO) through reactions with appropriate reagents. This versatility makes it a foundational chemical for numerous industries, including pigments, ceramics, and even electronics. Its applications as a depilatory agent in leather tanning and a vulcanizing agent in rubber manufacturing further underscore its industrial importance. Our expertise as a Barium Sulfide manufacturer ensures that the material we produce is optimized for these demanding uses.

For procurement managers and chemists, understanding the underlying chemistry of Barium Sulfide is key to effective utilization. Choosing a reliable CAS 21109-95-5 supplier that emphasizes product quality and transparent manufacturing processes is vital. We, as a leading Barium Sulfide manufacturer in China, are dedicated to providing materials that meet rigorous standards, ensuring that your industrial grade Barium Sulfide purchase contributes positively to your production outcomes.

In conclusion, the chemistry of Barium Sulfide – its ionic nature, reactivity, and synthesis pathways – makes it a cornerstone chemical for many industrial sectors.
