ABSTRAK
The purpose of this work is to synthesize whisker silicon carbide using rice hull from Indonesia. The rice hull was taken .from the area of Yogyakarta, Indonesia. The synthesis was started with coking the rice hull at 900"C for I hour without contact with air. After coking, the specimens was reacted at 1500"C in an electric furnace in argon atmosphere, the flow rate of argon flow was kept around 2 liter/min. The process was continued by treating the specimen in a boiling of MOH solution to separate the SIC whisker with the silica, and finally heating the specimen at 800°C to eliminate the excess of carbon. The final product was silicon carbide whisker in the form of long SiC whisker and a small part in the form of wool like SiC whisker
Key words: Rice hull, long SiC whisker, wool-like SiC Whisker
