MANUFACTURE OF POLYCRYSTALLINE TRANSPARENT YAG CERAMIC FOR SOLID LASER

摘要

PURPOSE: To find out a means to relatively simply manufacture a transparent YAG ceramic being of excellent quality at the optical properties by adding various laser light emitting elements. ;CONSTITUTION: One or more kinds among a lanthanide element and Cr, Ti elements are added to the Al₂O₃ and Y₂O₃ powder whose purities are &i99.9wt.% and respective specific surface areas are 1-50m²/g and 5-100²/g and the oxide components of Li₂O, Na₂O, MgO, CaO and SiO₂ as the sintering auxiliaries are added in the range of 50-10000ppm if one of them is used or in the range of 50-20000ppm if ≥ two kinds are used, and they are kneaded and compacted and then fired at 1600-1850°C.;COPYRIGHT: (C)1993,JPO&Japio
