Sintering to Transparency of Polycrystalline Ceramic Materials

“…YAG has been considered a prime candidate for its use as a matrix in oxide-oxide composites in gas turbine engines (Mah et al, 2004). Also, it can be used as substrate for dielectric components, prisms and mirrors, as a part of discharge lamps, high intensity lamps as well as an active medium for the production of lasers (Ikesue et al, 1995), since it is able to accept trivalent cations in its structure, especially rare earths and transition metals. In this sense, YAG can be doped with Yb 3+ for diode-laser (Takaichi et al, 2003), with Er 3+ (Qin et al, 2004) widely used in medical applications or Eu 3+ (Shikao et al, 2001) used as cathode ray tube.…”

Fabrication and optical properties of a highly transparent Nd:YAG ceramic

“…Compared with Nd:YAG single crystals, the Nd:YAG ceramic technology has the advantages of easy fabrication, size scalability, multifunctionality, high dopant concentration, and better homogeneity [6][7][8][9]. The first transparent Nd:YAG ceramics for laser materials was produced by Ikesue et al using a solid-state reaction method in 1995 [10]. Since then, the fabrication of transparent YAG ceramics has attracted more and more attention.…”

Simple Method for Synthesizing Aluminum-Yttrium Garnet (Nd:YAG) Nanopowders by Flushing (Bubbling) with Ammonia

“…This method requires a high firing temperature and prolonged soaking times [11]. Compared with solid-state reactions the method of wet chemical synthesis has such advantages as not only a low synthesis temperature and short firing duration, but also the fact that in the course of their use it is possible to obtain a uniform mixture of metal ions at an atomic level.…”
