Abstract
Compacted samples of Y2O3-V2O5 – MgO Nano –
particles wt. % sintered at different sintering temperature (700, 900, 1100, 1300) ) C° for 2
hours under static air were investigated by x-ray diffraction and differential thermal analysis(DTA), to identify the
phase present .Microstructure examination achieved by scanning electron microscopy
.Sintered density
and porosity were measured for all sintered samples .Compression was tested too and the Brake
down voltage and dielectric strength were measure for all sintered samples .The clear improvement were noticed in
both microstructure and damage characterization respectively after existing the MgO
Nano-particles,
by increasing in about 30% in sintered density and 25% for the compressive strength .The improvement
also noticed on both brake down voltage and dielectric strength.
