Chemical Structure
Basic Info
Antimony sulfide is a compound composed of antimony and sulfur elements. Its chemical formula is Sb₂S₃. It is a gray-black or reddish-brown powder. Its natural form mainly exists in the mineral stibnite. Its crystal structure is orthorhombic, with good thermal stability and conductivity. Antimony sulfide is insoluble in water, but soluble in strong acid. It decomposes into antimony and sulfide at high temperature and is an important inorganic compound.
Antimony sulfide is often used as a pigment, glass colorant, and component of matches and fireworks. It is also widely used as a lubricant additive and semiconductor material in the industrial field. In addition, antimony sulfide exhibits good friction performance and wear resistance in friction materials (such as brake pads), so it has important practical value.

Friction Materials
Antimony sulfide is one of the core components of friction materials (such as brake pads and clutch plates). Its chemical properties give it excellent stability and performance under high temperature and high pressure conditions:
Thermal stability: Antimony sulfide can maintain its chemical structure under high temperature conditions, reducing performance degradation caused by overheating during friction.
Friction regulation: As a solid lubricant additive, it can adjust the friction coefficient to ensure that the friction material can brake effectively without excessive wear.
Wear resistance: Antimony sulfide extends the service life of friction materials by reducing wear on the surface of the material, and is particularly suitable for high-speed or high-temperature working environments.
Pigment and glass manufacturing
Antimony sulfide plays an important role in the pigment and glass industry:
Pigment manufacturing: Its reddish-brown or black characteristics make it an important raw material for the manufacture of dark pigments, which are widely used in the fields of ceramics and coatings.
Matches and Fireworks
Antimony sulfide is widely used in match heads and fireworks manufacturing due to its flammability and reaction stability:
Match head raw materials: Antimony sulfide reacts with oxidants in the friction surface of matches to provide a rapid and stable ignition effect.
Fireworks combustion aid: In fireworks, it can adjust the burning rate and spark effect, while improving the brightness and color performance of fireworks.
Lubricants and alloy materials
Industrial lubricants: Antimony sulfide is used as a solid lubricant additive and is suitable for high-temperature and high-pressure equipment, such as aircraft engines, turbines and bearing systems.
Semiconductors and optical materials
Because antimony sulfide has narrow bandgap semiconductor properties, it has potential applications in the fields of optics and electronics:
Infrared detection: Antimony sulfide films can be used in infrared sensors and optoelectronic devices.
Optical components: It has certain experimental application value in the manufacture of special optical components (such as filters).
