摘要： An electrical device having first and second electrodes and a layer of a conductive composite electrically in contact with the first and second electrodes. The conductive composite is a mixture of a semi-crystalline polymer and a conductive filler, the conductive filler including a plurality of particles containing an inner material including a first metal; and an outer material surrounding the inner material, the outer material including a second metal; and an intermetallic compound formed between the inner material and the outer material. The intermetallic compound has features from the inner material and the outer material. The device can be a circuit protection device. Also provided is a method of making a conductive composite by dry mixing the components.
