Abstract :The microstructure, dielectric properties and electrical characteristics of Ni plated Si 3 N 4 powders were investigated using specimens produced by tube furnace sintering at 800-1200°C temperature. A uniform nickel layer on Si 3 N 4 powders was deposited prior to sintering using electroless plating technique. A composite consisting of binary additions, a metallic phase, Ni within a matrix of Ni has been prepared under Ar shroud and then tube furnace sintered. XRD, SEM insert ignore into journalissuearticles values(Scanning Electron Microscope);, Empedans Phase Analyzer were used to obtain structural data and to determine electrical properties such as dielectric and conductivity at the temperature range of 25-400C. The ferromagnetic resonance varied from 10 Hz to 1 GHz and measurements were employed to characterize the properties of the specimens. Experimental results carried out for composition insert ignore into journalissuearticles values(33 Si 3 N 4 );66Ni at 1200°C suggest that the best properties as 75,81HB and permittivity were obtained at 1200°C
