Chemische Eigenschaften
finely divided white powder(s) or crusty material; readily absorbs CO2 and H2O from the atmospheric; made by heating LiOH to ~800°C in a vacuum or by thermal decomposition of lithium peroxide; used in ceramics and special glass formulations and in lithium thermal batteries [HAW93] [MER06] [KIR81] [FMC93]
Verwenden
Lithium oxide is a strong alkali that absorbs carbon dioxide and water
from the atmosphere. It is used in manufacturing ceramics and special types of glass.
synthetische
Industrial and laboratory preparations. Only small volumes of material are prepared
industrially. Both industrial and laboratory preparations require the thermal decomposition
of lithium peroxide or of lithium hydroxide.
Lithium peroxide, Li202 , is converted to lithium oxide, Li20, and oxygen by heating
to 450° in a stream of helium gas.
Thermal dehydration of lithium hydroxide is carried out at 675°C±10° under vacuum
in a nickel container lined with silver foil.
Lithium carbonate may be converted to lithium oxide and carbon dioxide by heating
the material to 700°C under vacuum in a platinum boat.
Industrial uses. There are no current industrial uses which consume large quantities of
lithium oxide.
Lithium oxide reacts with water as it dissolves to form a solution of lithium hydroxide.
Lithium oxide is a strong base and reacts typically with acidic gases and liquids to form
lithium salts. At elevated temperatures, lithium oxide also reacts with many solid nonmetal
oxides (Si02, B2O3, etc.) and metal oxides (A1203 , Fe2C>3, etc.). High-temperature
reactions are the basis for the fluxing action of lithium oxide, lithium hydroxide and
lithium carbonate. Care must be taken to avoid the reaction of lithium oxide with reaction
vessels at high temperatures.
Allgemeine Beschreibung
Lithium oxide is a white crystalline solid. Its a strong base. It reacts with water and forms lithium hydroxide.
