Abstract

IN A PROCESS FOR THE PRODUCTION OF SILICON FROM RAW QUARTZ IN A ELECTRIC LOW-SHAFT FURNACE, IN WHICH THE ELECTRIC LOW-SHAFT FURNACE IS CHARGED WITH THE RAW QUARTZ IN GRANULAR FROM TOGETHER WITH BRIQUETTES OF A QUARTZ/CARBON REDUCING AGENT HAVING EXCESS CARBON IN RELATION TO THE REACTION SIO2 + 3C =SIC + 2CO, THE QUARTZ IN THE BRIQUETTED REDUCING AGENT IS FIRST CONVERTED TO SIC AT A TEMPERATURE BELOW 1600?C IN AN UPPER SECTION OF THE FURNACE, AND THE MOLTEN RAW QUARTZ IS THEN REDUCED AT A TEMPERATURE ABOVE 1600?C IN A LOWER SECTION OF THE FURNACE, AND USE IS MADE OF BRIQUETTED REDUCING AGENT HAVING AN EXCESS OF MORE THAN 50WT.ARBON IN RELATION TO THE RECTION SIO2 + 3C = SIC + 2CO, AND THE BRIQUETTED REDUCING AGENT IS CONVERTED TO SIC PLUS ACTIVATED CARBON AT A TEMPERATURE BELOW 1600?C IN THE UPPER SECTION OF THE FURNACE, AT WHICH STAGE THE BRIQUETTES OF REDUCING AGENT ASSUME A COKE-LIKE STRUCTURE, AND THE MOLTEN RAW QUARTZ IS REDUCED PARTLY BY THIS ACTIVATED CARBON AND PARTLY BY THE SILICON CARBIDE AT A TEMPERATURE ABOVE 1600?C IN THE LOWER SECTION OF THE FURNACE. THIS PROCESS ATTAINS A HIGH SILICON YIELD AT A LOWER ENERGY CONSUMPTION
