The use of antimony dates as far back as 5000 years ago when ancient Egyptians used antimony-based chemicals to make eye shadows and medicines. By the middle ages, antimony was widely used in alchemy. Today, most antimony is used in the form of antimony trioxide (Sb 2 O 3 for use as a flame retardant ingredient. Metallic antimony is used as an ...

It can be prepared by dissolving antimony, antimony trioxide, antimony trisulfide or antimony oxychloride in hot, concentrated sulfuric acid. 2 Sb (s) + 6 H 2 SO 4 → Sb 2 (SO 4) 3 + 3SO 2 + 6 H 2 O Uses. Owing to its solubility, antimony sulfate has uses in the doping of semiconductors.
Antimony trioxide, also known as antimony oxide or Sb 2 O 3, is the most widely produced compound of elemental antimony.The nations that produce the most antimony trioxide are China, South Africa, Bolivia, Russia, Tajikistan, and Kyrgyzstan. Typical applications for antimony trioxide include flame retardant synergist for use in plastics, rubber, paints, paper, textiles, and electronics ...
Antimony trioxide is a pure white ultra-fine powder in cubic crystal system. It is the most stable compound of antimony, with the molecular weight 291.5 and melting point 656℃, cubic crystal type (a stable type) has the density of 5.3g/cm3. Antimony trioxide is also named antimony white, and belongs to amphoteric oxide.
Antimony trioxide has been used as a white pigment since ancient times. The pigmentation from antimony oxide in plastics can be controlled and adjusted by the judicious selection of a Sb 2 O 3 grade having a specific particle size. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity.

Antimony Trioxide, Sb 2 O 3 was known in ancient times; it is probably referred to by Pliny under the name of stibia femina, and by Basil Valentine under the name flores Antimonii. The latter name was subsequently applied to the product derived from the roasting of antimony sulphide. Antimony trioxide occurs naturally in the minerals senarmontite and valentinite, and in certain other more ...

Due to the chemical affinity of arsenic and antimony, we analyzed the potency of antimony(III)-oxide (Sb(2)O(3)) to exert As(2)O(3)-like effects. Based on the same molar concentrations, lower efficacy in apoptosis induction and caspase-independent decrease of mitochondrial membrane potential was observed for Sb(2)O(3).
