Low temperature and microwave dielectric properties of TiO2/ZBS glass composites
چکیده انگلیسی

TiO2 based ceramic/glass composites were prepared by a non-reactive liquid phase sintering (NLPS) using zinc borosilicate (ZBS) glass having the deformation temperature of 588 °C. The compounds of Zn2SiO4 and Zn4B6O13 were formed after the sintering process, indicating that the ZBS glass was a non-reactive one in this system. For TiO2/50 vol% ZBS glass composite, the two-stage sintering behavior was conducted as the sintering temperature increased. The former might be correlated to the NLPS process and the latter appeared to be related to the crystallization. The dielectric constant (ɛr) was mainly affected by the porosity and obeyed the logarithmic mixing rule. The quality factor (Q × f0) showed an increase and then a steep decrease after the maximum at 850 °C. TiO2/50 vol% ZBS glass composite sintered at 900 °C demonstrated 36 in the dielectric constant (ɛr) and 7500 GHz in the quality factor (Q × f0) for an application to LTCC filters.
