Proposal of a composition model for commercial AlN powders

Mechanism and kinetics of combustion-carbothermal synthesis of AlN nanopowders

“…These excellent properties make AlN an extremely practical material for electronic application [2,4]. In particular, AlN has been widely applied in heat-dissipation field for its outstanding thermal conductivity [5,6].…”

Decomposition of aluminum oxynitride compounds in an air-vapor medium at 950°C

“…This formula does not satisfy the elec troneutrality condition (+3 -1.94 -2.4 = -1.34). Such "charged compositions" are encountered in the literature [8,16]. The representative points of these compositions, with the general formula АlО х N у , typi cally lie beyond the Аl 2 О 3 -А1N join of the ternary system Al-O-N [16].…”

“…The oxidation of AlN powders in air was studied in the range 800-1050°C [6] and at higher temperatures: from 1150 to 1750°C [7]. Work by Li et al [4] was similar in purpose to that by Ponthieu et al [8], who studied the composition and structure of AlN manufactured in different countries. Abid et al [9] were interested in the hydrolysis of AlN films on the GaAs semiconductor from the viewpoint of semicon ductor protection against oxidation.…”

Preparation and processing of doped AlN nanopowders

“…Aluminium nitride ceramics is an attractive material for electronics industry due to high thermal and very low electrical conductivity and the thermal expansion coefficient similar to silicon [ 1 ]. High melting point, good thermal stability and corrosion resistance of molten aluminium and cryolyte ensure a growing application of AlN in other fields.…”
