Latest Patents

Koyama holds a patent for a sintered ceramic body. This invention allows for the preparation of high-quality ceramic bodies by sintering a binary powder mixture at an exceptionally low temperature of 1000°C or below. The mixture consists of 30-50% by weight of a non-glassy phase of aluminum oxide and 70-50% by weight of a glassy phase. This glassy phase has a quaternary composition of silicon dioxide, boron oxide, aluminum oxide, and alkaline earth metal oxides, with at least 60% being strontium oxide. The resulting ceramic body exhibits high mechanical strengths, low dielectric constants, and excellent resistance to metal migration when in contact with metal parts.
