Antimony sulfide powder

Black or gray-black powder, rhombic crystal structure. Antimony sulfide is a black solid powder made from stibnite through careful selection and chemical purification. Its melting point is relatively low, which is 548℃, antimony oxide generated after high temperature decomposition, and metallic antimony generated in the presence of reducing agent.

Main performance:
1. It can prevent the oxidative combustion of materials at high temperature, maintain the friction stability of materials and improve the burning resistance of materials;
2, it can also reduce the decomposition speed of organic adhesive at high temperature, improve the service life of materials, and play the role of high-temperature inorganic adhesive and lubricating friction regulator.
3. In addition, the hardness of antimony sulfide and high-temperature reaction during braking is relatively low, which can reduce the noise and vibration generated by friction materials during braking.
4. Antimony sulfide has outstanding performance of adjusting friction coefficient, lubricating at low temperature below 200℃, stabilizing friction coefficient at high temperature of 250℃, and resisting recession.
5. In some disc formulations at home and abroad, it is found that the use of antimony sulfide can play the role of high-temperature inorganic binder, thus reducing the amount of resin.
6. The antimony sulfide produced by our company has an ultra-fine particle size of 1600 mesh, which can increase the fluidity of the product, increase the specific surface area of the product and make it more fully used.
