Antimony Trioxide - Overview. Antimony trioxide is an inorganic compound with the formula Sb 2 O 3. It appears white in color and it is an odourless white crystalline powder, sparingly soluble in water. It is the most important compound prepared from antimony. It is found in nature and extracted from the minerals valentinite and senarmontite.

Tang and Jin (2007) have studied the production of antimony trioxide from antimony concentrate bearing high copper by pyrochemical process (1150–1350 °C) in a blast furnace, wherein the formation of antimony trioxide was facilitated through volatilization.

However, only the first three compounds have significance in industrial production with other oxides mostly being the transition product of various kinds of antimony production process. Antimony trioxide (Sb2O3, Mr291.50) is a dual-type substance including cubic crystal and monoclinic crystal type.

It is separated from arsenic by the boiling of the arsenic trioxide before the antimony trioxide boils. Antimony trioxide can also be made by a two step process. Stibnite is burned in air with calcium chloride to make calcium sulfate and antimony trichloride, which is reacted with water to make antimony trioxide

Antimony, which is a silvery and brittle nonferrous metal, has poor electrical and thermal conductivities and is mainly used in alloys, fire retardents glass, etc. Antimony resources are mainly distributed in five countries all over the world, namely, China, Tajikistan, Bolivia, Russia, and South Africa, and their production accounts for more than 97% of the world.1,2 …

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.

An aqueous stabilized antimony pentoxide sol composition, comprising from 25% to 35% antimony pentoxide, from 6.5% to 17% of an amine and the remainder water, has been prepared. A dried composition obtained from this sol composition has also been prepared. The dried powder contains from 62% to 76% antimony pentoxide, from 17% to 32% of an amine and …

Tang and Jin (2007) have studied the production of antimony trioxide from antimony concentrate bearing high copper by pyrochemical process (1150–1350 °C) in a blast furnace, wherein the formation of antimony trioxide was facilitated through volatilization. Inevitably, the pyrochemical process is a severe source of environmental pollution and ...

Antimony oxide can be prepared by two processes, the direct and the indirect process. Indirect process In this process, antimony metal or ores is melted in a furnace to give ATO vapors. The vapors are quenched with air and cooled to convert the vapor to white powder. These powders are further filtered to give antimony trioxide powder.

Antimony ore. Antimony is nonmalleable, hard and brittle and can be crushed to a powder. Compared with metals, antimony is a poor conductor of electricity and heat. Antimony is the 63rd-most abundant element in Earth's crust. It is less abundant than tin, arsenic and the rare earths, but more so than bismuth, mercury and silver.
