ABSTRACT:
According to one exemplary embodiment, a dielectric ceramic composition includes a main component group, where the main component group is represented by MgxCayZnzTiO2+x+y+z, where the sum of x, y, and z is less than or equal to 1.0 such that the dielectric ceramic composition has a wider sintering temperature range and reduced exaggerated grain growth. According to one embodiment, x can be greater than 0.0 and less than 1.0, y can be greater than 0.0 and less than 1.0, and z can be greater than 0.0 and less than 1.0. The dielectric ceramic composition can further include between 0.0 and 50.0 percent by weight of aluminum oxide. The dielectric ceramic composition can further include copper oxide. The dielectric ceramic composition can further include boron oxide.
