Abstract:
Silicon nitride (Si3N4) is an advanced structural ceramic material which is being used for engineering applications such as heat engines and gas turbines. In this laboratory scale study, carbothermic production of silicon nitride from rice husks was investigated in detail. A highly pure mixture of carbon and silica was obtained by pyrolysis of water washed and acid leached rice husks from Turkey's Black Sea region. The obtained mixture was then treated in a tubular electric resistance furnace at a temperature range of 1300-1500 degrees centigrade under nitrogen flow rate of 50L/h. The results indicated that it was possible to produce Si3N4 from Turkish rice husks at the optimum nitridation conditions experimentally determined.
