Abstract:
Dual‐phase dielectric ceramic samples of Mg2SiO4/Ba(AlSiO4)2 were fabricated by ceramic injection molding (CIM), and they were systematically compared with the ones fabricated by conventional powder pressing (CP). It was found that by tuning the processing parameters, CIM samples with density, microstructure, grain size, and phase composition comparable with the CP counterparts can be produced. With optimized processing parameters, CIM samples with a relative density of 94.2% were accomplished, along with homogeneous phase distribution and uniform grain size. Meanwhile, satisfactory dielectric properties were also achieved (a dielectric constant of 6.67, a temperature coefficient of −0.94 ppm/°C, and a quality factor of 352,000 GHz). Moreover, a demonstrator with various blind holes and slots was fabricated by the CIM method, which exhibited good geometrical integrity, uniform microstructure, and consistent mechanical properties.
