Glycol–nitrate combustion synthesis of fine sinter-active yttria

Spray combustion synthesis of nanocrystalline Y2O3 and its thermodynamical and morphological study

“…Although they do have some advantages, the time-consuming precipitation or aging processes limit their industrial applications. Recently, combustion method became a popular way to produce nanophosphors [5][6][7][8][9][10]. The experimental procedures adopted in all of these combustion methods require pre-heated muffle furnace [8], hot plate at temperatures at about 773 K [9] or continuous heating apparatus [10].…”

Produced from the viscous, gel-like precursor [9], nanoparticles tend to agglomerate densely, forming fractal structure [11] become relatively hard to be separated.…”

Hierarchical Nanoceramics for Industrial Process Sensors

“…Fuel choices have included urea [Kingsley 1988, Sousa 1999, Mimani 2001, Civera 2003, Basu 2004, citric acid [Basu 2004, Schafer 1997, Roy 1999, Deshpande 2004 , hydrazine , Deshpande 2004, Ekambaram 1995, polyvinyl alcohol [Ma 2006], hexamethylenetetramine [Mimani 2001, Nagaveni 2004, oxalyldihydrazide [Mimani 2001, Nagaveni 2004, Aruna 1998] and others. Of specific interest to this study, ethylene glycol [Dasgupta 2001MatSci&Eng, Dasguputa 2002SSI, Chen 2006MatLett, Chen 2006 MatSci&Eng] has recently been used as an ACS fuel, as well as in other novel powder synthesis techniques [Bonet 1999, Uekawa 2002. The most commonly used fuel for ACS is glycine [Mimani 2001, Deshpande 2004, Nagaveni 2004MRB, Purohit JNucMatls 2001, Peng 2002, Erri 2004, Mukasyan 2007, which has been used extensively to produce perovskite oxides [Chick 1990, Basu 2004, Yang 2000, Mukasyan 2001, Wang 2006, Striker 2007, Nair 2008.…”

Eu:Y2O3 nano-phosphor prepared by novel energy-saving solution combustion method

“…Rare-earth oxides are one important category of optical materials because of their excellent physical, chemical and luminescent properties. Combustion method [9][10][11][12][13][14] is a preferred method that has been used to prepare all kinds of rare-earth oxides. In this case, rare-earth nitrate as oxidizer and different fuels have been used, resulting in nano-sized powder.…”

“…After heattreatment of the as-prepared product ranging from 773 K to much higher temperature, impurities were removed and larger nanocrystals were obtained. However, the experimental procedures adopted in all of these combustion methods require pre-heated muffle furnace [12], hot plate at temperatures of about 773 K [13] or continuous heating apparatus [14]. Produced from the precursor with honey-like consistency [13], nano-crystals tended to agglomerate densely, forming fractal structure [15] and are relatively hard to separate.…”
