Antimony: a metallic cleanse of the Middle Ages | Office ...

Feb 15, 2017· Concentrations are less than the 5 parts per billion safety limit. Antimony does not occur in nature in its metallic form, so where did Middle Age physicians get it? Like most metals, antimony has to be smelted from its ore, in this case antimony sulfide, also known as stibnite, a substance that has been known for thousands of years.

Antimony - Wikipedia

Antimony trioxide is formed when antimony is burnt in air. In the gas phase, the molecule of the compound is Sb 4 O 6, but it polymerizes upon condensing. Antimony pentoxide (Sb 4 O 10) can be formed only by oxidation with concentrated nitric acid. Antimony also forms a mixed-valence oxide, antimony tetroxide (Sb 2 O

Antimony Oxide - an overview | ScienceDirect Topics

Antimony ions have high affinity towards water (Table 10.3). Polymer chains of PbO 2 particles and agglomerates, on the other hand, are hydrated. Consequently, antimony ions would be readily bonded to hydrated polymer chains to form a polymer network. It is therefore appropriate to …


* Antimony Trioxide may damage the kidneys, liver and heart. IDENTIFICATION Antimony Trioxide is a white, odorless crystalline (sand-like) powder. It is used as a flame-proofing agent, in pigments and ceramics, to stain iron and copper, and to decolorize glass. REASON FOR CITATION * Antimony Trioxide is on the Hazardous Substance List

Antimony Trioxide,Sb2O3, 99.5%, CERAMIC/GLASS SUPPLY, 500 ...

Antimony(III) oxide also dissolves in concentrated mineral acids to give the corresponding salts, which hydrolyzes upon dilution with water.[4] With nitric acid, the trioxide is oxidized to antimony(V) oxide.[5] When heated with carbon, the oxide is reduced to antimony metal.

USAC Flame Retardant Theory - usantimony.com

Usually three to four parts of halogenated flame retardants are used to one part of antimony oxide on a weight basis. Using more than the 4: 1 ratio offers little additional protection. The stoichiometric ratio of chlorine to antimony in antimony trichloride is 3: 1.

USAC Antimony Uses and Formulations

Paints - Paints can be made flame retardant by providing a halogen, usually chlorinated paraffin or rubber, and 10% to 25% antimony trioxide. Additionally antimony oxide is used as a color "fastener" in paint subject to ultraviolet radiation that tends to deteriorate colors.

Antimony – Pure Water Products, LLC

Antimony is a toxic, lustrous grey semi-metallic element. Antimony trioxide is the most common compound form, used as a flame retardant. It's also found in batteries, pigments, glass and ceramics. Antimony enters drinking water as a result of human activity, especially through coal burning and the smelting of antimony-containing ores.

antimony | Definition, Symbol, Uses, & Facts | Britannica

Antimony is also used as an alloy in solder. Highly purified antimony is used in semiconductor technology to prepare the intermetallic compounds indium, aluminum, and gallium antimonide for diodes and infrared detectors. Antimony compounds (especially the trioxide) are widely used as flame retardants in paints, plastics, rubber, and textiles.

Antimony trioxide - Wikipedia

Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.
