LTCC and Bulk Zn4B6O13-Zn2SiO4 Composites for Submillimeter Wave Applications

Dorota Szwagierczak et al.

Summary: The new zinc metaborate Zn4B6O13-willemite Zn2SiO4 composites show promise as materials for LTCC substrates in microelectronic circuits for submillimeter wave applications. Composites were found to exhibit low sintering temperatures, compatibility with Ag-based conductors, low dielectric constants, low dissipation factors, and weak frequency and temperature dependences of dielectric constant, with the composite containing 87% Zn4B6O13 and 13% Zn2SiO4 showing the best characteristics for LTCC submillimeter wave applications.

Cheng-Liang Huang et al.

Summary: Novel microwave dielectric ceramics Na2Mg5-xZnx(MoO4)(6) (x = 0-0.09) were synthesized for ULTCC applications, with the effect of Zn substitution on their properties systematically investigated. Microwave dielectric properties can be significantly enhanced by minutely substituting Mg with Zn, leading to high values of Qxf.

A detailed study of the substitution mechanism for improved zinc-borate: High-performance and its crystal structure variation

Rui Peng et al.

Summary: The study investigated the substitution properties of Mn2+ to Zn2+ for Zn3B2O6 ceramic at the atomic scale, revealing three available sites in the crystal for Mn2+ occupancy, with the substitution process for Zn3 site having the lowest formation energy. Additionally, ion-substitution in the ZnO4 tetrahedron resulted in changes to electron distribution and bond property, eventually improving the dielectric performance and densification of the Zn3B2O6 ceramic.
