摘要：
A method for producing a flowing silica composition including a sol-gel transfer, where redispersion is carried out. The redispersion includes adding, after having reached gel point of the sol-gel transfer, liquid into the gel formed by the sol-gel transfer, and the addition being made within a sufficiently short time period after reaching the gel point, to result, after mixing of the gel and the liquid, in a rheologically homogenous flowing silica composition, which is and remains injectable as such, or by short stirring <30 s, through a thin 22G needle. Also disclosed are flowing silica compositions and gels obtainable by methods of the invention, and uses of flowing silica compositions.
