Synthesis of nanocrystalline magnesium aluminate (MgAl2O4) spinel powder by the urea–formaldehyde polymer gel combustion route

Enhanced infrared transmittance properties in ultrafine MgAl 2 O 4 nanoparticles synthesised by a single step combustion method, followed by hybrid microwave sintering

“…Hence various fabrication techniques such as sol-gel citrate technique [5],ureaformaldehyde polymer gel combustion [6], mixed fuel combustion [7], microwave assisted combustion [8], coprecipitation [9][10][11], flame spray pyrolysis [12], molten salt method [13], pechini method [14], organic precursor method [15] have been employed for the synthesis of nanoparticles of MgAl 2 O 4 .However in all these processes either complex and cumbersome steps or prolonged multiple calcinations are essentially required to obtain phase pure nano powder.…”

Low temperature synthesis of nanocrystalline magnesium aluminate with high surface area by surfactant assisted precipitation method: Effect of preparation conditions

“…It has good thermal and mechanical properties, high hardness and low electrical loss [2][3][4]. These special properties make MgAl 2 O 4 a potential candidate for a variety of technological applications, such as substrate for solid-state electronic devices, refractory materials, high brightness phosphor screen and fiber-optic temperature sensors [5,6].…”

Effect of water to surfactant ratio (R) on the particle size of MgAl2O4 nanoparticle prepared via reverse micelle process

“…Using two-fuel mixtures instead of a single fuel ensures the formation of pure nanocrystalline MgAl 2 O 4 directly as a result of the combustion reaction without additional thermal treatment [9]. Prabhakaran et al [10] synthesized MgAl 2 O 4 spinel powder by the urea-formaldehyde polymer gel combustion route. Although several methods have been used for the synthesis of this material, some improvement or a suitable alternative route is required to obtain pure and homogeneous MgAl 2 O 4 powders at a relatively low temperature with small particle size.…”
