초록

In this paper, We described the effect of $MoO_3$ Addition and firing temperature on the microwave dielectric properties of $BiNb0_4$ ceramics. The specimens prepared by conventional mixed method was addicted by 0 - 0.03 wt% $MoO_3$ and fired at 860 - $950^{\circ}$ for 3hr. Density increased when $MoO_3$ is below O.Olwt% but decreased when over O.Olwt%. $BiNb0_4$ ceramics addicted with CuO 0.03wt % and $MoO_3$ 0.01 wt% showed microwave dielectric properties, Dielectric constant 37.5, Quality factor[Qx$f_0$]5500, Temperature coefficient of resonance frequency 15ppm/$^{\circ}$
