Abstract

La présente invention concerne un procédé et un agent de gravure pour gravure chimique en milieu humide de couches minces et de particules de TiO2, permettant un enlèvement défini de matière de la couche mince de TiO2, voire une diminution de calibre particulaire. Le procédé comporte plusieurs opérations. On commence par préparer un agent de gravure d'un pH supérieur à 13 et contenant à une concentration supérieure à 0,1 mole une base prise dans le groupe NH4OH, NaOH et KOH ou l'un de leurs mélanges, et H2O2 à une concentration inférieure à celle de la base. On établit une température au moins égale à la température ambiante. On plonge les couches minces ou les particules de TiO2 dans l'agent de gravure et on les y laisse tremper pendant une durée qui est fonction de la température et de la composition de l'agent de gravure. On retire du bain de gravure les couches minces ou les particules de TiO2 gravées. On les rince à l'eau distillée et on les fait sécher. Pour conserver la composition initiale de l'agent de gravure, on ajoute du H2O2 pendant le traitement de gravure.
