The study on fabrication of dielectric materials for low temperature co-fired ceramics

The borosillicate glass and TiO2 Composite for Low temperature co-sintering dielectric material whose sintering temperature was lower than 900 degrees C. In general, the dielectric loss of glass ceramics is larger than pure ceramics material; hence good dielectric properties were arrived by controlling the process parameter and adjusting the ratio of composites in glass ceramics. The experimental results showed the mainly dielectric properties of LTCC materials were as following: 4 < epsilon < 10, tan delta < 3x10(-3) (1 MHz), and the influence of resistant rate to the dielectric loss was important in the range of low frequency at room temperature, which the tan 6 < 2x10(-3) when the resistant rate was larger than 10(14)Omega(.)cm.
