Aluminium nitride by carbothermal nitridation

Effect of urea on the size and morphology of AlN nanoparticles synthesized from combustion synthesis precursors

“…9c-f]. It has already been reported [23,24] that the particle size and morphology of AlN, synthesized by carbothermal reduction method, are closely related to the size and morphology of aluminum sources in the precursors. It is evident that the particle-size distribution of ␥-alumina, prepared without urea, is wide in our system [Fig.…”

Combustion synthesis of hexagonal AlN–SiC solid solution under low nitrogen pressure

“…Aluminum nitride (AlN) is a promising advanced ceramic because of its excellent physicochemical properties, such as high thermal conductivity, high electrical resistance, low dielectric constant, low thermal expansion coefficient, good thermal shock resistance, as well as good corrosion resistance [2][3][4][5]. Therefore, AlN is especially considered for many heat-dissipation applications such as IC packaging materials, heat sink, and high thermally conductive composites.…”

Gas-phase combustion synthesis of aluminum nitride powder

“…Of those that do,/tiN is the most desirable for reasons of safety and cost [1]. As a ceramic, biN has a high electrical resistivity (r > 10 In t'l.…”

“…Carbothermal reduction is a batch process involving a high-temperature (1400-1800 *C-), solid-solid reaction between _dumina and carbon powders in a nitrogen .atmosphere, yielding biN powders with particle diameters of 0.01-3.0p,n [1,3]. bin production via direct nitridation is also a batch process and involves reacting aluminum powder with nitrogen gas at temperatures in excess of 1200 *C, to produce powders with par_cle diameters in the range of 0.3--12pm [3,4].…”
