Metal Sulfide

SULMICS series

The SULMICS Series is a newly introduced product line of various metal sulfides. We have already commenced industrial production of tin sulfide-based materials as alternatives to antimony sulfide, which is widely used as a solid lubricant in automotive brake pads. In addition, we are developing other metal sulfide products in response to market needs, and samples are available for evaluation. Please contact us if you are interested.

Tin(II) Sulfide (SnS)

Tin(II) sulfide (SnS) is used as a solid lubricant due to its excellent lubricating properties and is primarily added as a friction modifier in automotive brake pads. With a melting point of 880°C, it delivers stable friction performance under high-temperature conditions. Moreover, due to its theoretical capacity being nearly twice that of graphite anodes, it is also attracting attention as a potential anode material for lithium-ion batteries. Additionally, it is being explored as a raw material for solid electrolytes in all-solid-state batteries.

In addition to pure tin sulfide (SnS), we also offer higher-sulfur-content variants such as SnS + Sn₂S₃, and graphite-blended grades such as SnS + Sn₂S₃ + C, specifically designed for use in brake pad applications. Particle size can be adjusted according to your requirements—please contact us for more details.
