Antimony ingots are refined, cast blocks or bars of antimony metal, usually with a high purity level (typically 99.65%). They are the result of smelting and refining antimony ore, most commonly from stibnite (Sbâ??Sâ??). These ingots are used as a base material for various industrial applications.
Characteristics of Antimony Ingots:
Appearance: Silvery-white, brittle metal with a shiny surface
Form: Usually in rectangular bars or trapezoidal blocks
Purity: Common grades are:
99.65% (Grade 2)
99.85% (Grade 1)
99.99% (High Purity) for electronic and semiconductor applications
Melting Point: ~630C (1166F)
Density: ~6.7 g/cm
Brittle: Can be crushed into powder, not malleable
Uses of Antimony Ingots:
Alloy Production
Used with lead to make hard alloys for:
Lead-acid batteries
Bullet and shot casting
Cable sheathing
Bearings and solder
Increases hardness and mechanical strength
Flame Retardants
Melted down and processed into antimony trioxide (Sbâ??Oâ??), used in flame retardant materials for:
Plastics
Textiles
Electrical components
Electronics & Semiconductors
High-purity ingots used in:
Semiconductors
Infrared detectors
Microelectronics
Glass & Ceramics
Used to remove bubbles and act as a fining agent in the glass manufacturing process
Packaging & Trade:
Typically packed in:
25 kg, 50 kg ingots
1-ton wooden or steel strapped pallets
Exported globally, with China being the largest producer and exporter
Safety Note:
While metallic antimony is relatively stable, antimony compounds can be toxic if inhaled or ingested. Proper handling and safety protocols are essential during processing.
Antimony ore is a naturally occurring mineral that contains antimony (Sb), a lustrous gray metalloid. The most common form of antimony ore is stibnite (Sbâ??Sâ??), which has a metallic luster and a lead-gray color. Other less common ores include valentinite (Sbâ??Oâ??) and kermesite (Sbâ??Sâ??O).
Characteristics of Antimony Ore:
Main Mineral: Stibnite (Sbâ??Sâ??)
Appearance: Metallic luster, steel-gray to silver in color
Hardness: 2 on Mohs scale (very soft)
Density: 4.6 g/cm�³ (moderate)
Found in: Hydrothermal veins, often with quartz, arsenic, lead, and silver ores
Uses of Antimony and Its Ore:
Flame Retardants
Main Use: Over 50% of antimony output goes into making flame retardant compounds.
How: Antimony trioxide (Sbâ??Oâ??) is combined with halogenated compounds to inhibit fire spread in plastics, textiles, and electronics.
Alloying Agent
Used with lead to improve hardness and strength.
Applications:
Lead-acid batteries
Bullets
Cable sheathing
Bearings and solder
Semiconductors and Electronics.
Antimony is used in semiconductors, infrared detectors, and diodes due to its electrical conductivity properties.
Glass and Ceramics.
Used to decolorize glass and as an opacifier in ceramic enamels.
Medicine and Cosmetics (historical and niche)
Anciently used in kohl (eyeliner) and traditional medicines.
Modern use is limited due to toxicity.
Pigments.
Antimony compounds are used in some paints and pigments.
