What is antimony trioxide used for?
Typical applications for antimony trioxide include flame retardant synergist for use in plastics, rubber, paints, paper, textiles, and electronics; polyethylene terephthalate polymerization catalyst; a clarifying agent for glass; an opacifier for porcelain and enamel; and a white pigment for paint.
What properties does antimony have?
Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
Is antimony oxide basic or acidic?
Since antimony oxides are amphoteric oxides, they would show some interesting acid-base catalytic properties.
What is antimony trioxide made of?
Preparation. Antimony trioxide is made when antimony is made. Stibnite is heated with air to make antimony trioxide. It is separated from arsenic by the boiling of the arsenic trioxide before the antimony trioxide boils.
Is antimony trioxide a halogen?
Halogens are nonmetal elements from Group 17 in the new periodic table including fluorine, chlorine, bromine, iodine, and astatine. The other substance of concern in conventional flame-retardant systems is antimony trioxide.
What is antimony used for in everyday life?
Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. Other uses of antimony alloys include type metal (in printing presses), bullets and cable sheathing. Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery.
What is unique about antimony?
Antimony (Sb) has an atomic number of fifty-one, with fifty-one protons in the nucleus. It is a highly brittle, bluish-white, semi-metallic element. Interesting Antimony Facts: Its name is attributed to the French word for “monk killer,” since toxic antimony is linked to alchemy, which was often studied by monks.
What makes antimony unique?
Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength.
Is antimony trioxide a flame retardant?
Antimony trioxide itself has no flame retardant function, however, when it is used together with halogenated compounds, the synergistic effect of the mixture creates the flame retardant properties.
Is antimony trioxide halogenated?
ANTIMONY TRIOXIDE HALOGENATED FLAME RETARDANTS NON-HALOGENATED FLAME RETARDANTS ETC. Antimony Trioxide is widely used as flame retardant synergist for various plastics.
Is antimony trioxide banned?
The chemicals banned under the bill include Tris, Antimony trioxide, Hexabromocyclododecane, Chlorinated parrafins, PentaBDE, and others.
