ABSTRACT |
Dielectrics used as capacitor was studied in the system of $Pb(MgW)_{0.5} O_3-PbTiO_3-PbZrO_3$ Curie tempera-tures of $PbTiO_3 PbZrO_3$ and $Pb[MgW]_{0.5} O_3$ were 49$0^{circ}C$ 23$0^{circ}C$ and 39$0^{circ}C$ respectively. When these materials formed solid solution the more amount of $Pb(MgW)_{0.5}O_3$ was increased the more Curie temperature lowered and dielectric constant increased. Higher dielectric constants were measured in the solid solution of which X-Ray diffraction patterns were changed. Especially Curie temperature and dielectric constant were 85$^{circ}C$ and 4159 respectively in the composition of 60 $Pb(MgW)_{0.5}O_3-30 PbTiO_3-10PbZrO_3$. Also in this composition ferroeletric material with thermal stability was obtained. |
