19 paź 2010 · Most treatment processes involve coating the surface of AlN particles with long chain organic molecules, such as carboxylic acids, particularly stearic acid, or through use of cetyl alcohol, n-decanoic acid, dodecylamine acid and so on (Egashira et al., 1991; Egashira et al., 1994).
For AlN powder, the reaction process is found during oxidation in temperatures ranging from 550 to 1100 °C [8,10,14,16]. For bulk specimens, the reaction process is found in the temperature interval from 1000 to 1390 °C [7,9,11–13, 15].
14 lut 2023 · Here, we characterise the effects of time (up to 12 h) and temperature (490 to 560 ∘C) on nitridation with the aim to establish an effective regimen for the controlled synthesis of an aluminium nitride reinforcement powder for the production of metal matrix composites.
5 sty 2017 · Different from the oxidation kinetics of other nitrides, the oxide layer on AlN can easily reach tens of micrometers at a temperature above 1200 °C. In the present study, the oxidation mechanism...
6 lip 2010 · A new waterproof technique for aluminum nitride powders could be developed by treating them in a stream of carbon dioxide gas containing saturated steam at room temperature.
