About Antimony Metal
Element of the nitrogen group; it occurs as crystal of triclinic system with silver white metal luster under normal temperature; fragile and lacking ductility and malleability; sometimes show phenomenon of fire; atomic valency is +3, +5; it burns with blue flames when heated in the air and generates antimony(III) oxide; power antimony will burn with red flames in the chlorine gas and generates antimony pentachloride; under the airless condition, it doesn’t react with hydrogen chloride or acid hydrochloric; soluble in aqua regia and acid hydrochloric containing a small amount of nitric acid; toxic

What is Antimony Ingot used for?
Antimony Ingot (Sb) - Applications and Uses
Antimony Ingot is a critical strategic metal with unique properties that make it indispensable across a wide range of modern industries. Its primary value lies in its ability to harden other metals, act as a flame retardant synergist, and serve as a key component in specialized chemical and electronic applications. Our high-purity Antimony Ingot is produced to meet the stringent specifications required for advanced manufacturing.
Primary Applications and Industries:
1. Flame Retardants & Safety
Antimony Trioxide, derived from Antimony Ingot, is the foremost synergist in halogen-based flame retardants.
* Function: It dramatically enhances the fire-inhibiting performance of materials, forming a protective char layer that suppresses combustion.
* Applications: Extensively used in plastics, textiles, rubber, and coatings for electronics enclosures, construction materials, automotive components, and children's toys to meet global fire safety standards.
2. Lead-Acid Batteries
This is the largest single market for Antimony Ingot.
* Function: Alloyed with lead in the battery grid plates, antimony significantly enhances mechanical strength, improves deep discharge recovery, and reduces water loss in traditional designs.
* Applications: Essential for starting-lighting-ignition (SLI) batteries in vehicles, as well as for deep-cycle batteries used in renewable energy storage and uninterruptible power supplies (UPS).
3. Alloy Hardening Agent
Antimony's classic role is as a hardening agent in various lead and tin-based alloys.
* Lead-Acid Battery Plates: As mentioned above, for structural integrity.
* Bearing Alloys (Babbitt Metal): Improves hardness, wear resistance, and load-bearing capacity in plain bearings for machinery and automotive applications.
* Solders: Used in specific solder alloys to increase strength and inhibit "tin pest" (the transformation of tin to a powdery form at low temperatures).
* Ammunition & Sheet Lead: Hardens lead for ammunition projectiles and for use in construction.
4. Semiconductors & Electronics
High-purity Antimony Ingot is crucial in advanced electronics.
* Semiconductor Dopant: Used as an n-type dopant in the production of semiconductor silicon and germanium wafers, precisely modifying their electrical properties.
* Compound Semiconductors: A key raw material for the manufacture of III-V compound semiconductors like Gallium Antimonide (GaSb) and Indium Antimonide (InSb), used in infrared detectors, lasers, and high-speed electronics.
5. Specialized Chemicals & Catalysts
* Polymer Catalysis: Serves as a catalyst in the production of Polyethylene Terephthalate (PET), the plastic used for bottles and textiles.
* Stabilizers: Used as a heat stabilizer in the production of polyvinyl chloride (PVC) to prevent degradation during processing and extend product life.
