Process for the Preparation of Finely Divided Precipitated Silica
Implementing Organization
Central Salt & Marine Chemicals Research Institute (CSMCRI)
Project Overview
A process for the preparation of precipitated silica having more than 75% particles finer than 10 nm on 5 kg batch scale has been developed. In the process neutral grade sodium silicate solution was treated with mineral acid and silica sol in different steps under controlled rate in presence of electrolyte.
