姜珩将 NH4 Cl 与 KCl 的混合添加剂加入到原料中，在流动 N

Jiang Heng NH4 Cl and the mixing of the additive added to the feed of KCl, nitriding of aluminum powder under N 2 flow, additive decomposition during heating vaporized aluminum powder is porous like loose, while the crushing surface of the aluminum particles the nitride film, the aluminum nitride powder in order to achieve complete. <br>US PEI new toner added to the aluminum powder, ball milling the mixture, after the post-combustion decarbonization and dried to prepare a nano-sized ultrafine particles AlN N, nitride, product 2 1 400 ℃, since carbon powder is added to the absorbent and the barrier effect of the agent.

Jiang Yu adds the mixture of NH4 Cl and KCl to the raw material, nitride the aluminum powder under flow N 2, and the decomposition of the gasification of the additive in the heating process makes the aluminum powder porous and loose, while breaking the nitride film on the surface of the aluminum grain, thus achieving the complete nitride of the aluminum powder.<br>Nixinmei added tothe toner to aluminum powder, the mixture was ground and dried in 1 400 degrees C N 2 nitride, nitride products after late combustion decarbonization, the preparation of nano-scale ultrafine AlN particles, toner added to act as an absorbent and blocker.

Jiang Heng added NH4Cl and KCl mixed additives to the raw material, nitriding the aluminum powder under flowing N2. The decomposition and gasification of the additives during the heating process made the aluminum powder porous and loose. At the same time, it can break the nitriding film on the surface of aluminum particles, thus realizing the complete nitriding of aluminum powder.<br>Pei Xinmei added carbon powder to the aluminum powder. The mixture was milled and dried, and then nitrided in 1400 ℃ N2. The nitriding product was decarburized by combustion in the later stage, and nano AlN particles were prepared. The addition of carbon powder played the role of absorbent and barrier.
