Abstract: A material composition having a core-shell microstructure suitable for manufacturing a varistor having outstanding electrical properties, the core-shell microstructure of the material composition at least comprising a cored-structure made of a conductive or semi-conductive material and a shelled-structure made from a glass material to wrap the cored-structure, and electrical properties of the varistors during low temperature of sintering process can be decided and designated by precisely controlling the size of the grain of the cored-structure and the thickness and insulation resistance of the insulating layer of the shelled-structure of material composition.
