Silicic acid high purity was produced by passing sodium silicate solution under pressure through a column packed with ion exchange resin. The effect of sodium chloride concentration on the gel formation process was studied. We proposed that, besides amorphous sol, chain-like compounds were also ...
We have observed occurrence of fibrous products on gel surface in four-component system of KK (silicic acid sol)–H 2 O–HCl–NH 3 , KK–H 2 O–HCl–NaOH and KK–H 2 O–HCl–TEA (triethanolamine). Bundles of fibres occur in the system with NH 3 , sticks and needles in system wi...
