Antimony

Overview

Antimony – mostly in its natural mineral form stibnite (Sb₂S₃) – is an extremely valuable metalloid known for its characteristic silvery-gray luster, high melting point, and brittleness. It plays a crucial role in numerous industries, from electronics and energy storage to flame retardants, alloys, and modern manufacturing.

Antimony is known for its ability to enhance the strength, durability, and safety of other metals, making it indispensable for applications such as lead-acid batteries, refractory materials, and precision alloys. Its unique properties make it a cornerstone of modern industrial and safety innovations.

Applications

The unique properties of antimony make it an indispensable material in various industries:

Battery manufacturing:

Antimony is an important component of lead-acid batteries, particularly in the grid alloy of the battery plates. Its addition improves battery performance by increasing cycle life and reducing self-discharge. Therefore, it is essential for automotive and industrial batteries. Flame Retardants:

Antimony trioxide (Sb₂O₃) is frequently used as a flame retardant synergist, particularly in combination with halogenated flame retardants. It is crucial for the production of plastics, textiles, rubber, and electronics that must be fire-resistant for safety reasons. Alloy Strengthening:

Antimony is often alloyed with lead, tin, and other metals to increase their hardness, strength, and corrosion resistance. These antimony alloys are essential for the manufacture of ammunition, bearings, solders, and cable sheathing, where increased durability and reliability are critical.

Pigments: Antimony compounds are used to produce pigments such as Naples Yellow (antimony lead yellow), which is widely used in paints, ceramics, and plastics due to its luminous and color-stable properties. Production of Antimony Trioxide: Antimony ore is also processed into antimony trioxide (Sb₂O₃), a fine white powder used as a synergist in flame retardants. This compound is an integral part of the production of plastics, textiles, rubber and electronics, improving their safety and fire resistance.
