More Information
Summary:Provided is a rare-earth gallium garnet ceramic which has a high extinction ratio and a high light transmittance. Ge and Al are incorporated as sintering aids into a rare-earth gallium garnet ceramic in amounts of 5-500 mass ppm and 20-250 mass ppm, respectively, in terms of metal amount. La présente invention concerne une céramique grenat à base de terres rares et de gallium qui présente un taux d'extinction élevé et une transmittance de la lumière. Ge et Al sont incorporés comme adjuvants de frittage dans une céramique grenat à base de terres rares et de gallium en quantités de 5 à 500 ppm en masse et 20 à 250 ppm en masse, respectivement, en termes de quantité de métal.
