What is Antimony Trisulphide?
Antimony Trisulphide (Sb₂S₃) is a grayish-black to predominantly black powder or crystalline solid with a high refractive index coupled with flame-retardant properties. It occurs naturally as the mineral stibnite and is also manufactured. This compound is used in Pyrotechnics, Friction materials, and Pigments in paint and is valued across industries.
Common Applications
- Pyrotechnics: Included in military-grade and commercial fireworks due to its ability to create bright, glittering effects.
- Ammunition Primers: Serves as an important composition of percussion caps and primer.
- Friction Materials: Used in brake pads and clutch linings to improve heat resistance and control friction.
- Glass Ceramics: Used as a refining agent to control the oxidation and removal of air bubbles.
- Matches Safety Fuses: Main usage in the ignition compoud of safey matches and delay fuses.
- Pigments: Used in some certain red and black pigments for coating and plastics.
