DEVELOPMENT OF Si2N2O, Si3N4 AND SiC CERAMIC MATERIALS USING RICE HUSK

DEVELOPMENT OF Si2N2O, Si3N4 AND SiC CERAMIC MATERIALS USING RICE HUSK

The formation of SiC from coked rice husk and Si3N4 and Si2N2O from HCl treated rice husk was observed at 1200-1400 C under N2 and NH3 atmospheres, respectively. The chemical analyses of the raw rice husk and products are tabulated. The XRD analyses show the presence of different phases in the produ...

Zusammenfassung:The formation of SiC from coked rice husk and Si3N4 and Si2N2O from HCl treated rice husk was observed at 1200-1400 C under N2 and NH3 atmospheres, respectively. The chemical analyses of the raw rice husk and products are tabulated. The XRD analyses show the presence of different phases in the products. A new mechanism for the development of these ceramic materials is proposed. 10 refs.
