Based on the properties of Titanium Diboride (TiB 2 ) combined with the knowledge of electrical engineering, a novel application of TiB 2 in the field of electric power has been proposed. The contact resistance of the particulate matter changes greatly when the external stress changes. Therefore, particulate matter can be used as a variable resistor in the field of fault current limiting. First, the pressure-resistance characteristics of TiB 2 were studied experimentally, and the law of resistance change with pressure was summarized. The explanation was given from the perspective of particle mechanics. Then, combined with the operating mechanism, a device with variable resistance was fabricated. And the curve of material resistance with time was tested. Finally, the material was passed through current, which proved that the material properties have not changed under large current. Thus the feasibility of the application of the material in the power field was verified.
