A facile preparation of temperature-stable borate ultra-low permittivity microwave ceramics for LTCC applications

Novel copper borate ceramics with lithium-based sintering aids for LTCC terahertz applications

“…Due to the relatively low sintering temperatures and appropriate dielectric properties, some borates are in the field of interest. [9][10][11][12][13][14] Over the last decade, the crystal structure, electronic transitions, magnetic and dielectric properties of copper borates have been studied by several authors and the broad potential of these materials including magneto-optical, piezoelectric, multiferroic, and photocatalytic applications has been considered. [15][16][17][18][19] However, the possible use of copper borates as microwave substrates has scarcely been investigated.…”

Sintering, Microstructure, and Dielectric Properties of Copper Borates for High Frequency LTCC Applications

“…Recently, with the tendency to decrease the sintering temperature, new materials have attracted more attention. Besides molybdates, tungstates, and phosphates, some borates are good candidates for new materials with a low sintering temperature [13][14][15][16][17][18][19][20][21][22][23][24].…”
