ABSTRACT:
A method is described for making silica gel having a large active surface area suitable for use as an adsorbent-separator of gases and liquids in hermetically sealed acid accumulators and as a filler in the fabrication of rubber articles.
The method produces silica gel having a large active surface area and, at the same time, a microgranular structure. The product is in the form of aggregates having a size which generally does not exceed 5 mm, so no additional grinding of the product is required. The silica gel exhibits a large pore volume.
