Silicon carbide, its chemical name SiC or the trade name carborundum, is a unique man-made material that has become a pillar of modern engineering. Silicon carbide powder is created by combining silicon and carbon at very high temperatures. Almost every bit of silicon carbide abrasive powder used in factories today is produced in large electric furnaces.

Silicon carbide (SiC) powder used as a deoxidizer in steelmaking, a high-performance abrasive, or a critical component in electric vehicle (EV) power electronics, SiC offers a unique combination of hardness, thermal conductivity, and chemical stability.

Silicon carbide powder is a raw material used in powder metallurgy; specifically, black silicon carbide is typically employed for processing materials with lower tensile strength—such as cast iron and non-ferrous metals—as well as non-metallic materials like stone and leather. In contrast, the higher-purity green silicon carbide is more frequently utilized for the precision grinding of hard and brittle materials, such as cemented carbides (tungsten carbide), optical glass, and high-quality ceramics.

Ferrosilicon nitride and silicon nitride sound like two very similar products, but in fact, they are fundamentally different. This article will explain the difference between the two from different angles.

Electrolytic manganese flake (often called EMM or electrolytic manganese metal) is a high-purity manganese material produced through an electrolytic refining process. Thanks to its stable composition, low impurity profile, and consistent flake form, EMM is widely used in steelmaking, aluminum alloys, high-nickel cathodes, lithium manganese oxide, NMC, chemicals, and other industrial applications. As demand for battery-grade manganese accelerates, electrolytic manganese flake is increasingly essential for producers seeking performance, quality, and cost-effective supply.

Ferrosilicon powder is a finely milled alloy of iron and silicon, typically containing 15%–90% silicon by weight. In industry, common grades include FeSi 45, FeSi 65, FeSi 75, and specialized low‑aluminum or low‑carbon variants. Thanks to its strong deoxidizing power, silicon activity, and controllable particle size distribution, ferrosilicon powder is widely used in steelmaking, foundry processes, magnesium production, welding consumables, cored wire, mineral processing, metallurgy fluxes, and even in certain chemical and battery precursor routes.
