• Chemische Eigenschaften

  Antimony trioxide is a noncombustible, odorless, white crystalline powder.

• Chemische Eigenschaften

  White or gray mineral, sometimes pale red, white streak and adamantine or silky luster. Mohs hardness 2–3.

• Physikalische Eigenschaften

  Occurs as colorless orthorhombic modifications, valentinite, or colorless cubic form, senarmontite; density 5.67 g/cm³ (valentinite), 5.20g/cm³ (senarmontite); cubic modification is dimeric consisting of Sb2O6 discrete molecules; refractive index 2.087; melts in the absence of oxygen at 656°C; boils at 1,550°C (sublimes); sublimes in vacuum at 400°C; very slightly soluble in water, insoluble in organic solvents; soluble in HCl, caustic alkalies and tartaric acid.

• Occurrence

  Antimony trioxide occurs in nature as minerals, valentinite [1317-98-2] and senarmontinite [12412-52-1]. It is used as a flame retardant in fabrics; as an opacifier in ceramics, glass and vitreous enamels; as a catalyst; as a white pigment in paints; as a mortar in the manufacture of tartar emetic; and in the production of metallic antimony.

• Verwenden

  Antimony Trioxide (commonly referred to as antimony oxide), Sb2O3 is used to impart flame retardancy to plastics. Although antimony trioxide is found in nature, it is too impure to be used. Flameretardant grades of antimony oxides are manufactured from either antimony metal or the sulfide ore by oxidation in air at 600–800 °C. The particle size and chemical reactivity is determined by the processing conditions, enabling the production of several different grades. Antimony trioxide is from 99.0–99.9 wt % Sb2O3. The remainder consists of 0.4–0.01 wt % arsenic; 0.4–0.01, lead; 0.1–0.0001, iron; 0.005–0.0001, nickel; and 0.01–0.0001, sulfates. It is insoluble in water and the loss on drying at 110 °C is 0.1 wt % max.
  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 Sb2O3 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. Translucent plastics can be made by using low tint grades with relatively large particles.

• Verwenden

  Antimony oxide, Sb2O3, is a nonreactive white pigment prepared from metallic antimony using a similar technique to that used for the preparation of zinc oxide.
  Antimony oxide is widely used in the preparation of fire retardant paint in conjunction with chlorine containing resins. On exposure to fire, the chlorine gas liberated by decomposition of the resin component of the paint film reacts with the antimony oxide to produce a vapor of antimony chloride that blankets the flames. Antimony oxide is also used to modify the heavy chalking characteristics of anatase form of titanium oxide.

• Verwenden

  manufacture of tartar emetic; as paint pigment; in enamels and glasses; as mordant; in flame-proofing canvas.

• synthetische

  Antimony trioxide is obtained by roasting stibnite:
  2 Sb₂S₃ + 9 O₂ → 2Sb₂O₃ + 6SO₂
  Temperature and air feed is carefully controlled in the process to suppress any formation of antimony tetroxide (Sb₂O₄). Antimony trioxide is separated from any arsenic trioxide (As₂O₃) that may be present as an impurity by volatilization, as the latter is much more volatile than the former. It may be also prepared by alkaline hydrolysis of antimony trichloride and subsequent dehydration of hydrous oxide under controlled heating (rapid or vigorous heating may partially oxidize Sb(III) to Sb(V).
  Antimony trioxide also may be made by heating the metallic element with oxygen or air. The volatilizing trioxide is condensed and collected.

• Definition

  A white insoluble solid. It is an amphoteric oxide with a strong tendency to act as a base. It can be prepared by direct oxidation by air, oxygen, or steam and is formed when antimony(III) chloride is hydrolyzed by excess boiling water.

• Allgemeine Beschreibung

  Diantimony trioxide is a white crystalline solid. Diantimony trioxide is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Diantimony trioxide is used to fireproof fabrics, paper and plastics, as a paint pigment and for many other uses.

• Biochem/physiol Actions

  Machado-Joseph disease, also known as spinocerebellar ataxia-3, is an autosomal dominant neurologic disorder. The protein encoded by this gene contains (CAG)n repeats in the coding region, and the expansion of these repeats from the normal 13-36 to 68-79 is the cause of Machado-Joseph disease. There is a negative correlation between the age of onset and CAG repeat numbers. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

• läuterung methode

  Dissolve the trioxide in the minimum volume of dilute HCl, filter, and add six volumes of water to precipitate the basic antimonous chloride (free from Fe and Sb2O5). The precipitate is redissolved in dilute HCl, and added slowly, with stirring, to a boiling solution (containing a slight excess) of Na2CO3. The oxide is filtered off, washed with hot water, then boiled and filtered. The process is repeated until the filtrate gives no test for chloride ions. The product is dried in a vacuum desiccator [Schuhmann J Am Chem Soc 46 52 1924]. After one crystallisation (precipitation), the oxide from a Chinese source had: metal (ppm) Al (8), Ag (0.2), As (56), Cr (6), Ge (0.4), Mn (0.2), Na (16), Ni (2.2) Pb (2.4), Sn (0.4) and V (32). It sublimes in a vacuum at 400o, being yellow on heating and pale buff in colour on cooling. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 615-616 1963.] Aqua regia. This is prepared by adding slowly concentrated HNO3 (1 volume) to concentrated hydrochloric acid (3 volumes) in a glass container. This mixture is used to dissolve metals, including noble metals and alloys, as well as minerals and refractory substances. It is done by suspending the material and boiling (EFFICIENT FUME CUPBOARD — EYE PROTECTION] to dryness and repeating the process until the residue dissolves in H2O. If the aqua regia is to be stored for long periods it is advisable to dilute it with one volume of H2O which will prevent it from releasing chlorine and other chloro and nitrous compounds which are objectionable and toxic. Store it cool in a fume cupboard. However, it is good laboratory practice to prepare it freshly and dispose of it down the fume cupboard sink with copious amounts of water.

• Inkompatibilitäten

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, halogenated acids, chlorinated rubber, bromine trifluoride. Reduction with hydrogen forms toxic antimony hydride.

• Waste disposal

  Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
