Latest Patents
Hiroshi Nakamura holds a patent for a "Method of producing a light-transmitting spinel sintered body." This invention describes a polycrystalline spinel sintered body that excels in light transmission, making it suitable for use in infrared light-transmitting windows with a thickness of 2 mm or more. The method involves hot pressing high-purity spinel powders at temperatures ranging from 1,200°C to 1,700°C and pressures between 100 to 500 kg/cm². This process compacts the sintered body to achieve a density of 95% relative to the theoretical density. Following this, the sintered compact undergoes a hot isostatic pressure treatment at temperatures of 1,400°C to 1,800°C and pressures of 500 kg/cm² or more. The result is a high-density sintered body with excellent light transmission, surpassing prior art methods.
