“…[1][2][3][4] In LTCC, a sintering temperature lower than the melting points of the inner metals and suitable microwave dielectric properties (an appropriate relative permittivity " r , a high quality factor Q Â f , and a nearzero temperature coefficient of resonant frequency f Þ are strongly required for practical applications. [5][6][7][8] Thus, searching for novel microwave dielectric ceramics with low sintering temperatures and promising properties is still a hot issue.…”

Single phase Li 2 W 2 O 7 with anorthic structure was prepared by the conventional solid-state reaction method at 550 C and the anorthic structure was stable up to 660 C. The dielectric properties at radio frequency (RF) and microwave frequency range were characterized. The sample sintered at 640 C exhibited the optimum microwave dielectric properties with a relative permittivity of 12.2, a quality factor value of 17,700 GHz (at 9.8 GHz), and a temperature coefficient of the resonant frequency of À232 ppm/ C as well as a high relative density $94.1%. Chemical compatibility measurement indicated Li 2 W 2 O 7 did not react with aluminum electrodes when sintered at 640 C for 4 h.

Abstract:High performance low temperature co-fired ceramic (LTCC) dielectrics is highly desired for next generation information technology. The rational design is a key issue for the development of new LTCC materials. In comparison to the design of conventional electroceramics, more attention should be paid on the formation process of the material structure for that of LTCC, in addition to the physical properties, due to the special requirement in fabrication processing. In this paper, sintering mechanism of three types of LTCC materials, i.e., glass-ceramics, glass ceramic composite, and glass bonded ceramics, as well as important factors of their dielectric properties are discussed and summarized, and the design strategies for LTCC dielectrics, based on new matrix materials with much lower sintering temperature or higher quality, are proposed. As an example for rational design, oxyfluoride glass-ceramic based dielectrics, a new class of LTCC materials with low ε r , is analyzed.
