Abstract
A dielectric porcelain composition includes MgTiOand MgSiOand satisfies a+b=1 and 0<b<1, wherein a denotes a molar ratio of MgTiOand b denotes a molar ratio of MgSiO. It can include MgTiOand CaTiOand satisfy a+c=1 and 0<c≦0.15, wherein a has the same meaning as shown above and c denotes a molar ratio of CaTiO. It can also include MgTiO, MgSiOand CaTiOand satisfy a+b+c=1, 0<b<1 and 0<c≦0.15, wherein a, b and c have the same meanings as shown above. These compositions can be manufactured, with the content of MgSiO, the content of CatiOand the contents of MgSiOand CaTiOadjusted, respectively. These compositions can be used as dielectric materials to manufacture dielectric resonators.
