Apr 13, 2018· Bismuth Oxide is weakly astringent with supposed antiseptic properties and has a protective action on mucous membranes and raw surfaces. Zinc Oxide is an astringent and mild antiseptic and probably owes its actions to the ability of the zinc ion to precipitate protein but other mechanisms may be involved.

Read MoreStructure. Phosphorus pentoxide crystallizes in at least four forms or polymorphs.The most familiar one, a metastable form (shown in the figure), comprises molecules of P 4 O 10.Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in spite of the high symmetry of the molecules, the crystal packing is not a close packing).
Read MoreAn oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O 2– (molecular) ion. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2. Most of the Earth''s crust consists of solid oxides, the result of elements being oxidized by the ...

Read MoreLead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element ...
Read MoreLithium oxide is produced by thermal decomposition of lithium peroxide at 300-400°C. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen: 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C. 2 Li ...
