Silicon powder ( %, particle size ) was ballmilled in an attritor ballmill at 400 rpm for 30 h in hexane. It was found that slurry of ballmilled silicon in hexane was produced as a result of the milling. This slurry was sprayed into a silica tube at high temperature (800±1100℃) under an argon atmosphere.
