METHOD OF OBTAINING POWDERS OF OXIDE LITHIUM-TUNGSTEN BRONZES

摘要

FIELD: chemistry.SUBSTANCE: invention can be applied in the chemical industry. Powders of oxide lithium-tungsten bronzes are obtained in heating of an initial composition, which includes tungsten (VI) oxide and lithium tungstate, to temperatures of 570-600°C, 30-minute exposure with further increase of the temperature to 650-700°C and 1-hour exposure. The composition additionally contains lithium tetraborate and metal tungsten powder with the following component ratio, wt %: LiWO- 30-66; LiBO- 7-24; WO-20-34; W - the remaining part.EFFECT: claimed method makes it possible to obtain highly-disperse powders of oxide lithium-tungsten bronzes without vacuuming the reaction zone at relatively low temperatures.7 ex
