Abstract
A method for making a superconducting fullerine composition, includes reacting a fullerine with an alloy, and particularly reacting C.sub.60 with a binary alloy including an alkali metal or a tertiary alloy including two alkali metals in the vapor phase. Also, a Cesium-doped fullerine high T.sub.c superconducting composition has the formula Cs.sub.x C.sub.60, and particularly Cs.sub.3 C.sub.60. Also, a homogeneous bulk single phase high T.sub.c superconducting composition has the formula (Rb.sub.x K.sub.1-x).sub.3 C.sub.60.
Claims16
A method for making a superconducting fullerene composition having the formula (M).sub.x C.sub.60 wherein x is in the range between about 1.5 and about 3 and wherein M is one or more alkali metals, comprising reacting a C.sub.60 fullerene with an alloy wherein said alloy is a binary alloy containing an alkali metal or a ternary alloy containing at least two different alkali metals.
