Sintering behavior and microwave dielectric properties of Li2O and In2O3 doped zinc orthosilicate having the composition ofZn1.9Si1.05O4, i.e. the Zn1.9-2xLixInxSi1.05O4 system where x = 0.01~0.06,were investigated. The liquid phase occurred by sinteringcontributed to the densification. As the amount of Li2O and In2O3 increased, the temperature indicating the maximum valueof bulk density in each composition decreased from 1250 oC to 1050 oC. And the value of dielectric constant against sinteringtemperature showed a similar tendency. Also, the value of quality factor decreased as the amount of Li2O and In2O3 increased. The dielectric constant and the quality factor of the composition of x = 0.02 sintered at 1150 oC were 6.49 and 55,437 GHz,respectively.
Abstract
Sintering behavior and microwave dielectric properties of Li2O and In2O3 doped zinc orthosilicate having the composition ofZn1.9Si1.05O4, i.e. the Zn1.9-2xLixInxSi1.05O4 system where x = 0.01~0.06,were investigated. The liquid phase occurred by sinteringcontributed to the densification. As the amount of Li2O and In2O3 increased, the temperature indicating the maximum valueof bulk density in each composition decreased from 1250 oC to 1050 oC. And the value of dielectric constant against sinteringtemperature showed a similar tendency. Also, the value of quality factor decreased as the amount of Li2O and In2O3 increased. The dielectric constant and the quality factor of the composition of x = 0.02 sintered at 1150 oC were 6.49 and 55,437 GHz,respectively.
