摘要
A study of the physicochemical properties of silica products formed in acid processing of the nepheline concentrate is reported. It was found that amorphous silica produced in precipitation of silicon dioxide from solutions obtained in sulfuric acid decomposition of nepheline occupies an intermediate position between white carbon and silica gel, whereas silica produced from gelatinized silica-containing solutions close in properties to silica gel. The morphology of silicon dioxide samples formed by various methods was studied and a comparative analysis of their structural-surface properties was made.
