Antimony trioxide poisoning can lead to increased serum alanine aminotransferase and aspartate aminotransferase activities. Antimony trioxide is classified as possibly carcinogenic, and some forms are potentially endocrine disrupting. [ 35 ] It is also used as a pigment and/or clarifying agent in certain glasses and ceramics. Antimony trioxide is commonly used as a catalyst in the production process. Antimony, in the form of tartar emetic, is not a poison which figures much in forensic medicine in most parts of the world, and it is Great Britain in particular which has an unenvi- able record in the criminal use of this drug. All of them are health threats. Antimony trioxide (Sb2O3, CAS 1309-64-4) is widely used as a flame retardant synergist in a number of household products, as a fining agent in glass manufacture, and as a catalyst in the manufacture of various types of polyester plastics. COMMON APPLICATIONS Oatey Bar Solder is a general purpose alloy of 50% tin and 50% lead.50/50 Bar Solder is most commonly used for copper drain piping, tin plating, seaming joints and sheet metal.50/50 Bar Solder can be used to solder copper and most copper alloys including lead, nickel alloys and steel. Antimony is Antimony containing products have certain toxicity, not only in the dyeing process cause environmental pollution, the end product also has pollution into the nature, so our products have a role in environmental protection.

Despite its utility, a fact worth considering is that the element is toxic. Increased exposure to the element can lead to antimony poisoning. Symptoms of this disorder are similar to those of arsenic poisoning. Low doses cause headaches, nausea, dizziness and depression. The effect of antimony trioxide (Sb2O3) catalyst on the solid-state polycondensation (SSP) of poly (ethylene terephthalate) (PET) has been rigorously studied. NOTE: About 85% of polyesters contain antimony, which is not allowed by GOTS. Antimony and many of its compounds are toxic.
