Abstract
Una mattonella adatta per l'impiego in un processo di fusione del silicio viene ottenuta formando una miscela di materiale carbonioso e fumi di silice, combinando la miscela con acqua, sottoponendo a formatura la miscela umidificata in una pressa a rulli ad anello o mediante un processo di estrusione, così da ottenere mattonelle successivamente indurite per essiccazione.Vengono così riutilizzati vantaggiosamente i fumi di silice e materiale carbonioso, sottoprodotti relativamente inutili per il processo di fusione del silicio.A tile suitable for use in a silicon melting process is obtained by forming a mixture of carbonaceous material and silica fumes, combining the mixture with water, forming the humidified mixture in a ring roller press or by means of a process of extrusion, so as to obtain tiles subsequently hardened by drying. The silica fumes and carbonaceous material, which are relatively useless by-products for the melting process of silicon, are thus advantageously reused.
