Antimony trioxide - Wikipedia

Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3 is the most important commercial compound of antimony is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb 2 O 3 dissolves in aqueous solutions with hydrolysis.A mixed arsenic-antimony oxide occurs in the nature as the very rare mineral stibioclaudetite.

Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air s physical and chemical properties are most similar to its heavier homologues strontium and barium is the fifth most abundant element in Earth''s crust, and the third most abundant metal, after iron and ...

Selenium - Wikipedia

Selenium is a chemical element with the symbol Se and atomic number 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic rarely occurs in its elemental state or as pure ore compounds in the Earth''s crust.

Carbon dioxide - Wikipedia

Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth''s atmosphere as a trace gas.The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm.

Annual Report (10-k)

Mar 31, 2021· The new price agreement was implemented in the third quarter of 2019, and resulted in lower antimony production costs and an improved cash flow for 2019 and better expectations for the North American operations going forward. The Company is currently engaged in a renewal of the contract with this supplier.

Xenon - Wikipedia

Xenon has atomic number 54; that is, its nucleus contains 54 protons.At standard temperature and pressure, pure xenon gas has a density of 5.761 kg/m 3, about 4.5 times the density of the Earth''s atmosphere at sea level, 1.217 kg/m 3. As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point. Liquid xenon has a high polarizability due to its ...

Polyethylene terephthalate - Wikipedia

Antimony. Antimony (Sb) is a metalloid element that is used as a catalyst in the form of compounds such as antimony trioxide (Sb 2 O 3) or antimony triacetate in the production of PET. After manufacturing, a detectable amount of antimony can be found on the surface of the product. This residue can be removed with washing.

Potassium - Wikipedia

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives.

Vanadium - Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery-grey, malleable transition metal.The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.. Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by ...
