Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O.PbO occurs in two polymorphs: litharge having a tetragonal crystal structure, and massicot having an orthorhombic crystal structure.Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components.
Mar 03, 2011· Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in the United States that produce antimony ...
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.

Thallium(III) compounds resemble the corresponding aluminium(III) compounds. They are moderately strong oxidizing agents and are usually unstable, as illustrated by the positive reduction potential for the Tl 3+ /Tl couple. Some mixed-valence compounds are also known, such as Tl 4 O 3 and TlCl 2, which contain both thallium(I) and thallium(III).
effects from drinking water containing antimony at the level measured in your drinking water as it is not substantially above the WHO health-based guideline value. Although there is some evidence in animals that inhalation of certain antimony compounds increased the risk of cancer, there are no data to indicate whether or not antimony can
other metals to form alloys. Antimony oxide is added to fabrics and plastics to make them fireresistant- . Antimony alloys are used in several products including batteries, solder, sheet and pipe metal, bearings, castings, ammunition and pewter. Antimony may also be released into the environment by incinerators and coal-burning.
