PROCEDIMENTO PER LA TRASFORMAZIONE IN FORME GRANULARI O MONOLITICHE DI PARTICELLE A BASE SILICEA

A method for converting siliceous base particles into granular or monolithic forms, comprising a step for aggregating the particles which provides a mass having a plastic consistency through the interaction of the siliceous base particles with an aqueous solution which comprises an alkaline metal hydroxide and a step for evaporating the water of the mixture, followed by a treatment for baking the mixture at a temperature which is capable of producing permanent bonds among the siliceous base particles.
