| description | The invention relates to a process for producing a silicate from a plant ash comprising crystalline silica. The process comprises reacting said plant ash with a base in the presence of an additive which is a salt comprising a multivalent anion. The invention also relates to a silicate obtainable from said process and to a process for preparing a precipitated silica from said silicate. The invention also concerns a reaction mixture which can be used for said processes.
L'invention concerne un procédé de production d'un silicate à partir de cendres végétales comprenant de la silice cristalline. Le procédé comprend la réaction desdites cendres végétales avec une base en présence d'un additif qui est un sel comprenant un anion multivalent. L'invention concerne également un silicate pouvant être obtenu à partir dudit procédé et un procédé de préparation d'une silice précipitée à partir dudit silicate. L'invention concerne également un mélange réactionnel qui peut être utilisé pour lesdits procédés. |
