Antimonsulfid

Is selects by the stibnite process with the chemically pure, for black solid powder. Its melting point quite is low, is 548 degrees Celsius, after the antimony oxide which the pyrolytic decomposition produces, as well as when reducing agent existence produces the metal stibium, can prevent when high temperature material oxidized burning, the maintenance material friction stability, enhances the material the anti-fever performance Also can reduce the organic bond in high temperature time disintegration rate, enhances the material the service life, its prominent function is adjusts the friction coefficient the performance, enables this material to obtain the widespread use in the profession.
