What is Antimony?

  • Antimony is a semi-metallic chemical element with an atomic number 51 and symbol Sb in the Periodic Table.
  • Latin name of Antimony is Stibium. It is usually found in two forms namely metallic form and non-metallic form.
  • Antimony compounds are used since ancient times as a component in cosmetics.
  • It is naturally found in Earthีšs crust in the ores of valentinite and stibnite.

Uses of Antimony

  • Pure antimony is used to manufacture certain semiconductors like infrared detectors and diodes.
  • It is used to harden lead and increase its durability.
  • Batteries consist of antimony for smooth functioning.
  • It is also used to make small arms & bullets.
  • It is a very good flame retardant.
  • Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes.
  • It is alloyed with lead or other metals to improve their hardness and strength. A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in printing presses) , bullets and cable sheathing.
  • Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery.

Properties of Antimony

  • The metallic form appears in a bright silver colour brittle and non-metallic form will appear as the grey powder.
  • It is a weak conductor of electricity and heat. The special feature of antimony and its alloys is that they expand on cooling.

Certain Health Facts About Antimony

  • It is toxic but does not have any harmful effects.
  • But constant exposure to this may cause some diseases like lung diseases, heart problems, and stomach ulcers.
  • Harmful effects of antimony upon body tissues and functions can occur following inhalation or ingestion of certain compounds of antimony. Such poisoning resembles arsenic poisoning.
  • Antimony poisoning has resulted from drinking acidic fruit juices containing antimony oxide dissolved from the glaze of enamelware containers.
  • The major toxic side effects of antimony as a result of therapy are cardiotoxicity and pancreatitis which is seen commonly in HIV and visceral leishmaniasis coinfections.

Question

What is the Element Antimony Used For?

Answer:

  • In its metallic form it is silvery, hard and brittle.
  • Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes.
  • It is alloyed with lead or other metals to improve their hardness and strength. A lead-antimony alloy is used in batteries.

What is SB in Periodic Table?

Answer:

Antimony (Sb) , a metallic element belonging to the nitrogen group (Group 15 [Va] of the periodic table) .

Is Antimony Toxic to the Body?

Answer:

  • Antimony toxicity occurs either due to occupational exposure or during therapy.
  • Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition, antimony trioxide is possibly carcinogenic to humans.
