What is the Antimony Melting Point?

Antimony Melting Point

Antimony is a versatile metallic element that boasts an array of allotropic forms. It naturally bears a brittle, lustrous appearance. As such, its common mineral form is the gray sulfide mineral stibnite (Sb2S3). Join us to discover more about antimony as we uncover its melting point,  properties, history, occurrence, and varied uses.


Element Properties

Antimony bears an atomic number of 51 with an atomic weight of 121.76. At its 630.5°C (1,166.9°F) melting point, antimony goes in a phase transition from solid to liquid state where it reaches a 1,380°C (2,516°F).

Boiling point. While its density at 20°C (68°F) is 6.691 grams/cm3, it has oxidation states of -3, +3, and +5. Finally,  its electron configuration is 1s 22s 22p 63s 23p 63d 104s 24p 64d 105s 25p3.



The historical significance of antimony dates back to ancient times. In ancient Egypt, antimony found its place within eye makeup. Antimony was utilized throughout history in alloys for various applications such as type, bells, and mirrors.



Antimony is found in more than a hundred different minerals, among the most important including stibnite (Sb2S3).

Stibnite deposits can be seen all over Algeria, China, Mexico, Peru, South Africa, and parts of the Balkan Peninsula as well as in Russia and Tajikistan, which were the main antimony producers until 2020.


Commercial Production and Uses

Commercially, antimony is synthesized by a wide range of processes, including the direct reduction of stibnite with iron and the electrolysis of sodium sulfide solutions. Its applications embrace a large variety of industries. It finds use in castings, type metal, automobile batteries, bullets, and chemical equipment.


Properties and Reactions

Antimony has interesting properties, displaying solidifying power similar to water – it expands when the temperature decreases and remains stable in dry air but slowly tends towards the formation of oxide in moist air.

Heating under sulfur or halogens can easily oxidize antimony and burn brilliantly with a blue flame emitting white fumes of Sb2O3 singlet oxidation product. The trioxide of antimony is soluble in both acids as well as alkalies.


Uses of Antimony

This powerful element takes center stage in diverse industries, from metallurgy to medicine. Strengthening alloys like lead and forming type metal, antimony proves its worth. As flame retardants, its compounds safeguard paints, plastics, and textiles.

The semiconductor world depends on antimony for diodes and infrared detectors. Not stopping there, it serves medicine as an expectorant and nauseant. Antimony is a true multitasker that powers batteries, sheathes cables, and elevates chemical equipment.


Health Effects and Environmental Impact

While antimony has many valuable uses, it is important not to ignore its potential health risks. Long-term exposure to antimony dust can irritate the eyes, skin, and lungs, resulting in lung diseases, heart problems, and stomach ulcers. As we begin accepting Antimon’s medicinal aspects, let us balance these with possible health risks that may be present.

Antimony’s presence in the environment leads to soil pollution, and it can be carried great distances through groundwater from surface waters, thus affecting. Animal tests have revealed its potential harm – lung damage, heart troubles – urging us to strike a delicate balance between progress and preservation.



So hence, the melting point of antimony, 630.5°C (1,166.9°F), marks a critical aspect of this captivating element with its historical significance and occurrence in nature along with versatile commercial applications.

However, we have to remain alert about probable health risks and Environmental impacts due to improper harnessing of its properties of antimony.

By responsibly harnessing its properties of antimony, the full potential for technological advancements and industrial innovations can be unlocked by us responsibly.
