    摘要: Aluminum nitride (AlN) is continuously produced by continuously carbonitriding a continuously replenished charge of alumina, for example successive charges of alumina/carbon extrudates, in a reaction zone comprising at least one conduit, the ratio of the exchange surface area/volume of which at least one conduit ranging from 5 to 50 m.sup.-1, preferably from 10 to 50 m.sup.-1, and continuously withdrawing product AlN therefrom.
