“…TSS is an efficient and economic method, which control the abnormal grain growth and improved the transmittance of YAG [44,45]. YAG sintered with the first-step sintering temperature at 1800°C and the second-step sintering temperature 1550-1600°C revealed more than 40% transmission [44,45]. Furthermore, neodymium-doped YAG (Nd:YAG) sintered via TSS exhibited excellent transmittance (85%) [65].…”

Sintering is a critical phase in the production of ceramic bodies. By controlling the density and microstructure formation, sintering now emerged as a processing technology of ceramic materials. Tailoring the structural, mechanical, electrical, magnetic and optical properties is widening the application of ceramics in various fields. Recently, many advanced sintering methods have reported to fabricate ceramic materials with controlled properties. Two-stage sintering (TSS) is one of the simple and cost-effective methods to obtain near-theoretical density materials with controlled grain growth without adding any dopants. Many recent works have reported the use of TSS as a processing method to fabricate nanoceramics for various applications. With this background, this chapter reviews the advantages of TSS in ceramic preparation based on properties and materials and explores the future directions.

“…To obtain Yb:YAG transparent ceramics with desired microstructure, its fabrication technology is very important. In recent years, many efforts have been made on YAG-based ceramics related to the synthesis of high-purity and agglomeration-free powders [8][9][10], amount and choice of sintering additives [11][12][13], optimization of sintering process [14][15][16], post-treatment [17][18][19][20], etc. Powder shaping technology was also important for obtaining highly transparent ceramics.…”

In this work, Yb:YAG transparent ceramics were prepared through aqueous gel-casting forming technique. Single-phase Yb:YAG nanopowders with mean particle size of 170 nm were used to prepare Yb:YAG slurries. The rheological properties of Yb:YAG slurries were investigated as a function of pH value and the dispersant content. It was found that the maximum zeta potential was achieved at pH = 11.5 with 2 wt% dispersant content (based on the weight of Yb:YAG powders). And then, the stable slurries with different solid loading (30-40 vol%) were prepared by ball milling and casted to form green bodies. The influence of the solid loading on microstructure of green bodies was investigated. The result showed that the green body with solid loading of 38 vol% had no deformation and exhibited homogeneous and compact microstructure with a relative density of 56.3 %.Finally, high optical quality Yb:YAG ceramic was obtained with the in-line transmittance of 81.2 % (1 mm thick). Graphical Abstract Highly transparent Yb:YAG transparent ceramics were prepared through aqueous gel-casting forming technique starting from the raw materials of single-phase Yb:YAG nanopowders.

“…In the process, the sample is first heated to a higher temperature to achieve an intermediate relative density (above 75%), and then rapidly cooled down and held at a lower temperature until it is fully dense (Z. Chen et al, 2008).…”
