A convenient method of producing porous silica particles is disclosed. The particles produced by the method can have impurity levels in the parts-per-billion range, and can have substantially uniform size. The particles are advantageously used to produce silica-containing glass bodies such as optical fiber preforms, silica tubes, lenses, rods and the like. The method comprises forming a silica-containing sol in a comminution means or forming such a sol and introducing it into a comminution means, causing a gel to form from the sol, and comminuting the gel in the comminution means such that substantially dry, porous particles result.
