Effect of Ni substitution on the microwave dielectric properties of cordierite
Cordierite (Mg 2Al 4Si 5O 18) is one of the silicates with low dielectric constant ( ɛ r), which are expected for good candidate of millimeter wave dielectrics. Microwave dielectric properties of Ni substituted cordierite solid solutions; (Mg 1− x Ni x ) 2Al 4Si 5O 18 have been investigated. (Mg 1−...
