Abstract
A gas atomization method is successfully applied for fiber and powder production from a highly viscous slag. The slag suction pressure becomes higher, when a flow guide was inserted at the exit of the gas nozzle. When the molten coal gasification slag temperature was 1500℃, a smooth continuous fiber measuring approximately 9μm in diameter was produced, which could be used as a heat insulating media and a buffer material. Powders having a diameters of approximately 9μm were produced at 1600℃, which could be used as raw material for cement.
