Metal containing compounds having a graphite-like layer structure are derived from poly(amino-s-triazine), [A], which has a layer structure and is represented by (C3N3)2NxHy, where 2</=x</=4, and 0</=y</=8. Reaction of [A] with a transition metal M at 400 DEG -1000 DEG C. gives a compound represented by CaNHbMc, where 0.6</=a</=20.0, 0</=b</=1.0, and 0.001</=c</=0.5. This compound exhibits magnetism. Reaction of [A] with a halide of a transition metal or aluminum at 200 DEG -500 DEG C. gives C6NpHqMrXs, where M is a transition metal or Al, X is a halogen, 8</=p</=10, 0</=q</=10, 0.6</=r</=1.5, and 0</=s</=1. When M is a transition metal the compound exhibits paramagnetism. When X is Al, heating of a powder of the compound at 800 DEG -950 DEG C. provides an AlN powder coated with an amorphous organic substance composed of C, N and H and, hence, protected against oxidation. The same coated AlN powder is obtained also by reacting a powder of [A] with an aluminum halide at 800 DEG -950 DEG C. By heating the coated AlN powder at a temperature above 1000 DEG C. the amophous organic coating sublimates and decomposes to leave a pure AlN powder which is suitable for sintering. |
