Latest Patents

Tomisako holds a patent for "Ceramics having excellent high-frequency characteristics and method of producing the same." This innovative ceramic composition includes SiO, Al2O3, MgO, ZnO, and B2O3 as constituent components. The ceramics contain 30 to 50% by weight of a crystal phase with ZnO and Al2O3, 5 to 15% by weight of a crystal phase with SiO and MgO, and 40 to 60% by weight of an amorphous phase primarily made up of SiO or SiO and B2O3. Notably, the content of the SiO crystal phase is limited to not more than 6% by weight. This unique composition results in a dielectric loss at 60 GHz of not larger than 15×10, showcasing excellent high-frequency characteristics and making it highly useful as an insulating substrate for high-frequency wiring boards.
