Tras la etapa b) se pueden llevar a cabo las siguientes etapas opcionales:
b’) eliminación de la materia orgánica mediante técnicas de decantación, recogida de sobrenadante o por reacción química con substancias oxidantes tales como peróxidos e hipoclorito de sodio.
5 b’’) eliminación más fina de los óxidos cristalinos y partículas duras no sujetas a modificación bien mediante procesos de centrifugación y/o gravimétricos en disolución o por turbo-secadores, preferiblemente por un proceso de centrifugado bien vía húmeda o vía seca seguido o no de un proceso de atomización con depresión controlada o mediante cualquier otro proceso de secado industrial
10 incluida la liofilización.
c) Obtención de finos laminares bien en suspensión líquida o en polvo bien mediante posterior secado por un proceso de centrifugado bien vía húmeda o vía seca seguido o no de un proceso de atomización con depresión controlada o mediante cualquier otro proceso de secado industrial incluida la liofilización.
15 Opcionalmente, se puede realizar una etapa de adición c’) a las estructuras laminares en al menos un paso, de precursores del tipo expansor (tabla 1).
