Carbonitriding reactions of diatomaccous earth: phase evolution and reaction mechanisms
Apstrakt
The possibility of using diatomaceous earth as Si precursor for low temperature synthesis of non-oxide powders by carbothermal reduction-nitridation was studied. It was found that carbonitriding reactions produce phases of the Si-Al-O-N system. Already at 1300 degrees C, nanosized, non-oxide powders were obtained. The comparatively low reaction temperatures is attributed to the nano-porous nature of the raw material. The evolution of crystalline phases proceeded via many intermediate stages. The powders were characterized by X-ray and SEM investigations. The results showed that diatomaceous earth can be a very effective source for obtaining non-oxide powders.
