Review on the Vapour-Phase Synthesis of Aluminum Nitride Powder Using Thermal Plasmas

Synthesis of Cubic Aluminum Nitride (AlN) Coatings through Suspension Plasma Spray (SPS) Technology

“…Some of the conventional synthesis methods of AlN powder involve the carbothermal reduction-nitridation of alumina [10], direct nitridation of Al powder [11], non-transferred arc plasma method [12], chemical routes [13], microwave-assisted urea route [14], pulsed laser ablation [15] and transferred type arc plasma [16]. Tables 2 and 3 summarize the different methods of producing AlN coatings and powder, respectively.…”

Understanding the growth of micro and nano-crystalline AlN by thermal plasma process

“…Details of thermal plasma produced AlN are summarized by Cruz et.al. in 1999 [13] and Iwata et.al. in 2004 [9].…”

“…This method provides high plasma power density, clean and controlled environment for material synthesis, single step synthesis, high throughput and industrial scale production capability. There are few reports on the successful synthesis of nano-powder of AlN using N 2 and NH 3 as a reacting gas by thermal plasma method [5,[9][10][11][12][13][14][15][16] however 100% nitridation in pure N 2 atmosphere has not been achieved. Details of thermal plasma produced AlN are summarized by Cruz et.al.…”

Numerical study of the synthesis of nanoparticles in an inductively coupled plasma reactor

“…The thermal plasma technology is considered as a suitable gas phase method to produce monodisperse nanoparticles [3]. A wide variety of metallic and ceramic nanoparticles have been synthesized in thermal plasma processes [3], [4], [5], [6]. Since these processes involve very fast and complex phenomena, modeling studies are an important tool to provide both, a better understanding of and to investigate the optimum process operation.…”
