FeS2

Product Name Name: FeS2 Product Overview This product is high-purity iron disulfide powder (Molecular Formula: FeS₂, CAS: 12068-85-8), commonly known as pyrite powder. It is prepared through high-purity ore selection, ultrafine grinding, precise classification and impurity purification processes with a standard particle size of 325 mesh. The powder features uniform particle size, no coarse particles, high purity and extremely low impurities. As a natural mineral iron disulfide with complete crystal structure and stable physical and chemical properties, it has excellent electrochemical activity, high sulfur and iron content, and uniform reaction activity. It is non-toxic, environmentally friendly and highly compatible. The 325-mesh fineness balances dispersibility and reactive specific surface area, avoiding incomplete reaction of coarse particles and agglomeration and oxidation risks of ultrafine powder. It is a high-quality basic functional material for battery energy storage, chemical synthesis, metallurgical additives and wear-resistant materials, suitable for industrial precision production and formula modification scenarios. Technical Parameter Appearance: Dark gray powder Particle size: 325 mesh Product Features 1 High Purity and Low Impurities with Excellent Stability: Processed from high-grade selected ore with FeS₂ purity ≥98% and sufficient sulfur and iron content, as well as extremely low impurities such as silica and ash. It effectively avoids electrochemical attenuation, uneven reaction and product defects caused by impurities. With complete crystal structure and stable physical and chemical properties, it is not easy to oxidize or decompose at room temperature and has high batch consistency, ensuring long-term stable operation of terminal products. 2 Precise 325-mesh Fineness with Excellent Adaptability: Standard 325-mesh ultrafine uniform powder with a pass rate of ≥99.5% and concentrated particle size distribution without mixed coarse and fine particles. The moderate fineness balances excellent powder fluidity, dispersibility and reactive specific surface area, adapting to various wet and dry production processes. It can be directly fed without secondary grinding, greatly improving production efficiency. 3 High Electrochemical Activity and High Reaction Efficiency: Natural pyrite crystal has high activity and sufficient sulfur content, featuring high discharge capacity, low polarization and good reversibility. As a cathode material for primary lithium batteries, it has excellent charge-discharge performance and cycle stability, serving as a preferred active material for low-cost and high-performance energy storage batteries. 4 Environmental, Non-toxic and Cost-effective for Industrialization: Non-toxic and harmless without heavy metal pollution, it complies with RoHS and REACH environmental standards with no harmful volatilization during production and use. With stable raw material sources and mature technology, it has lower cost and more stable performance than synthetic sulfides, suitable for large-scale industrial mass production. Application Fields 1 Cathode Materials for Primary Lithium Batteries: As the core cathode material for FeS₂ primary lithium batteries, it endows batteries with high specific capacity, low self-discharge and long storage life due to high sulfur content and high electrochemical activity. It is widely used in long-term power supply scenarios such as smart water meters, gas meters, temperature measuring equipment, security equipment and IoT passive devices. 2 Chemical Synthesis and Desulfurization Additives: Used for fine chemical vulcanization reactions and sulfur compound synthesis, serving as high-efficiency desulfurization catalysts and industrial desulfurization additives to improve desulfurization efficiency. It is also applicable to sewage treatment and waste gas treatment for environmental protection chemical production. 3 Metallurgical and Foundry Additives: Used as sulfur-based additives for special metallurgy and alloy smelting to accurately control the sulfur content of alloys and improve alloy cutting performance and microstructure. It can be used for deoxidation, desulfurization and modification in casting to improve the quality of metallurgical finished products. 4 Wear-resistant Materials and Filler Modification: Used as functional fillers for brake pads, wear-resistant rubber and engineering plastics to improve the wear resistance, high temperature resistance and impact resistance of materials. It can also be used for filling modification of anti-corrosion coatings and industrial primers to enhance the wear resistance and anti-corrosion performance of coatings. 5 Fireworks and Gunpowder Raw Materials: With stable combustion and sulfur release characteristics, it can be used as an auxiliary raw material for fireworks and gunpowder, suitable for the formula production of civil fireworks agents.
