Abstract

Procedimento per la preparazione di particelle sferiche porose di silice consistente sostanzialmente nell'emulsione un sol acido di silice in un mezzo disperdente, nel gelare le microgocce del sol allo stato emulsionato e nel sottoporre il gelo così ottenuto a trattamento termico in presenza del liquido emulsionante e della base di termico in presenza del sol.
