Antimony trioxide - Wikipedia

Global production of antimony(III) oxide in 2012 was 130,000 tonnes, an increase from 112,600 tonnes in 2002. China produces the largest share followed by US/Mexico, Europe, Japan and South Africa and other countries (2%). As of 2010, antimony(III) oxide was produced at four sites in EU27. It is produced via two routes, re-volatilizing of crude antimony(III) oxide and by oxidation of antimony metal. Oxidation of antimony meta…

Antimony Trioxide - an overview | ScienceDirect Topics

Antimony trioxide (ATO) is commonly used as a co-synergist with halogenated flame retardants to enhance their effectiveness. Recent comprehensive genotoxicity studies and a critical review by the European Commission have indicated that, contrary to the indications of earlier less well authenticated studies, antimony trioxide is not a genotoxic carcinogen.

Antimony Trioxide, Sb 2 O 3

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 ...

Particle Size Analysis of Antimonous Trioxide

Antimony trioxide, also called antimony white, has the formula Sb203 with a structure dependant on the temperature. It is used as a flame retardant, pigment, and catalyst. Antimony trioxide is mainly produced via the smelting of stibnite ore, which is oxidized to crude Sb2O3 using furnaces operating at approximately 850 to 1,000 °C.

US20150259216A1 - Method for producing antimony …

A method for producing antimony trisulfide can inexpensively produce antimony trisulfide that has a relatively low content of lead, arsenic, and crystalline silica (i.e., impurities). The method includes charging a reaction vessel with an antimony trioxide powder and sulfur, and heating the inside of the reaction vessel to react antimony trioxide with sulfur.

Synthesis and characterization of antimony oxide ...

Antimony trioxide (Sb2O3) nanoparticles with particle sizes ranging from 2 to 12 nm, spherical in shape, and well-distributed were successfully synthesized by chemical reduction method.

Antimony - Wikipedia

Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3. [6] : 758 Antimony is a silvery, lustrous gray metalloid with a Mohs scale hardness of 3, which is too soft to make hard objects; coins of antimony were issued in China's Guizhou province in 1931 but the durability was poor and the minting was soon discontinued.

Because antimony trioxide (ATO) used widely for PANVDC is suspected as a carcinogen, non-toxic zinc hydroxystannate (ZHS) could be the alternative for reduction of ATO usage. Moreover, a flame retardant efficiency of the combination of ATO with ZHS could be expected because it was reported that ATO resists flame in the gas phase, whereas ZHS reacts in the condensed phase.
