Reaction Sintering of Aluminum Nitride.

open access: yesJournal of the Japan Society of Powder and Powder Metallurgy, 1994
Aluminum nitride blocks were prepared by the usual method of powder metallurgy. The raw material is of ultrafine aluminum particles prepared by arc-prasma processing. The particles were pressed in a steel die, followed by two-step sintering (873K and 1473K) in flowing nitrogen under null pressure.The nitriding reaction of aluminum is exothermic, thus ...
