ABSTRACT:
A conductive wire is electrically heated in a gas atmosphere, wherein a gas reacts with a constituent material of the conductive wire, under gravity-free or micro gravity state. A ceramic is formed on a surface of the wire sa an outer core through a reaction between the wire and the gas and is left by caving an inside wire by melting while maintaining controlled gas convection.
