“…In the past, the general approaches for the production of AlN have been intensively studied. These works have been stimulated by the attractive properties of AlN, for example, its high thermal conductivity, thermal and chemical stability, low thermal expansion coefficient, low dielectric constant, good mechanical strength, wide bandgap, and non‐toxicity. The main disadvantages of traditional thermal synthesis methods are the long processing times, high impurity levels of O and C in the final material, and the lack of crucible materials with long‐term stability.…”

“…The main disadvantages of traditional thermal synthesis methods are the long processing times, high impurity levels of O and C in the final material, and the lack of crucible materials with long‐term stability. In contrast, plasma processes can provide new technological benefits, based on high energetic species, such as, for example, electronically and vibronically excited molecules, ions, and nitrogen atoms, forming reactive media well suited for the synthesis of AlN . In addition, the active control of plasma parameters has the potential to ensure the formation of AlN of high quality.…”

“…Jung et al [16] reported the modified carbothermal reduction process in which aluminum nitride (AlN) particles and whiskers were synthesized by heat treatment of aluminum gluterate complex under nitrogen flow in the temperature range 1200-1500 o C and then burning out the residual carbon. Novel synthesis methods such as pulsed laser ablation [17][18][19][20], electrochemical methods [21], low-temperature nitridation of metallic aluminum [22], the use of organometallic precursors, and vapor synthesis have been also reported for the preparation of nanocrystalline AlN [23][24][25][26][27].…”

“…[4][5][6] Conventional commercial methods for producing AlN, namely carbothermal reduction and direct nitridation, 7,8 are batch type processes and can yield micrometer size powders. Recently, some novel methods, such as pulsed laser ablation, [9][10][11][12] carbothermal synthesis, [13][14][15] electrochemical methods, 16 low-temperature nitridation of metallic aluminum, 17 the use of organometallic precursors, and vapor synthesis have been used to prepare nanocrystalline AlN. [18][19][20][21][22] One of the most promising and cost-effective methods for producing AlN powder is self-propagating high-temperature synthesis, or combustion synthesis.…”
