Abstract

The $0.96MgTiO_3-0.04SrTiO_3$ ceramics with $B_2O_3$(10wt%) were prepared by the conventional mixed oxide method. The structural properties were investigated with sintering temperature by XRD. According to the X-ray diffraction pattern of the $0.96MgTiO_3-0.04SrTiO_3$ ceramics with $B_2O_3$(10wt%), the ilmenite $MgTiO_3$ and perovskite $SrTiO_3$ structures were coexisted and secondary phase of the $MgTi_2O_5$ were appeared. In the case of $0.96MgTiO_3-0.04SrTiO_3+B_2O_3$(10wt%) ceramics sintered $1225^{\circ}C$, dielectric constant, quality factor and temperature coefficient of resonant frequency were 19.82, 62,735GHz, $-2.983ppm/^{\circ}C$, respectively.
