PROCESS FOR INCREASING THE SPECIFIC MASS AND IMPROVING THE HOMOGENEITY OF CHEVREL PHASE POWDERS AND CHEVREL PHASE WIRE OBTAINED ACCORDING TO THIS PROCESS

摘要

Chevrel phase powders are compounds of lead, molybdenum and sulphur (PbMo6S8). Additives composed of a metal, a mixture of several metals and/or a metal alloy, all of which have a low melting point less than the heat-treatment temperature of Chevrel phase powders or chemical transport agents, are introduced into said powders. The introduction may also be effected by coating Chevrel phase powders by a physical or chemical process. The wires obtained using this process are capable of generating powerful magnetic fields.
