Patent

CA 2566293

The invention relates to a method for producing spherical tungstic acid powder by acidifying an aqueous solution of alkaline tungstate with mineral acid at a high temperature, preferably in a continuously stirred tank reactor or a cascade of at least two continuously stirred tank reactors, and to tungstic acid thus obtained and characterised by a high bulk density and spherical morphology.

L'invention concerne un procédé permettant de produire un acide tungstique sphérique pulvérulent, par acidification d'une solution aqueuse de tungstate alcalin avec de l'acide minéral, à température élevée, de préférence dans une cuve mélangeuse à débit continu ou dans une cascade d'au moins 2 cuves mélangeuses à débit continu. L'invention concerne également l'acide tungstique ainsi obtenu, qui se caractérise par une densité en vrac élevée et par une morphologie sphérique.
