“…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.

“…Various wet-chemical methods have been developed and successfully used to synthesize pure and / or doped YAG. These involve precipitation [1,4,7,9,[14][15][16][17][18][19][20][21][22][23][24][25] , sol-gel [1,17,[26][27][28] , citrate gel [29] , hydrothermal [30] , solvothermal [6,31] , supercritical water [32,33] , combustion [34,35] , spray-pyrolysis [36,37] , microemulsion [38] , microwave irradiation [39] and modified Pechini routes [40] . Among them, precipitation method is one of the most commonly used techniques, because homogeneous multi-element compounds from which can be prepared effectively on a large scale and final products with improving phase purity can be formed at the temperature below 1000 °C.…”

Abstract. YAG powders were synthesized by co-precipitation and two-step moderate calcinations at 600 / 800 °C or 600 / 900 °C in air, respectively. Two kinds of the synthesized powders both possess pure cubic YAG phases without any secondary phases such as YAH, YAP and YAM, etc.. The former has low agglomeration with nano-sized primary particles and large active energy, and the latter has homogeneously dispersed and well-crystallized particles, with a narrow particle size distribution of 8 -13 μm.

“…[8][9][10][11] There are two primary approaches to the synthesis of nano-sized YAG phosphors. The first approach is a top-down method where bulk YAG synthesized by the conventional solid-state diffusion reaction technique is pulverized into nano-sized particles using ball-mill equipment.…”

Cerium-activated yttrium aluminate (Y 3 Al 5 O 12 :Ce 3+ ) exhibiting a garnet structure has been widely utilized in the production of light emitting diodes (LEDs) as a yellow emitting phosphor. The commercialized yttrium aluminum garnet (YAG) phosphor is typically synthesized by a solid-state reaction, which produces irregular shape particles with a size of several tens of micrometers by using the top-down method. To control the shape and size of particles, which had been the primary disadvantage of top-down synthetic methods, we synthesized YAG:Ce nanoparticles with a diameter of 500 nm using a coprecipitation method under the atmospheric pressure without the use of template or special equipment. The precursor particles were formed by refluxing an aqueous solution of the nitrate salts of Y, Al, and Ce, urea, and polyvinylpyrrolidone (55 K) at 100 °C for 12 h. YAG:Ce nanoparticles were formed by the calcination of precursor particles at 1100 °C for 10 h under atmospheric conditions. The phase identification, microstructure, and photoluminescent properties of the products were evaluated by X-ray powder diffraction, scanning electron microscopy, absorption spectrum and photoluminescence analyses.
