Title: Postopek za sintezo 4d in 5d (Nb, Mo, Ta, W) nitridov prehodnih kovin v obliki kvazi enodimenzionalnih struktur (SI), A process for the synthesis of 4d and 5d (Nb, Mo, Ta, W) nitrides of transition metals in form of quasi-one-dimensional structures (ENG)
Description: The subject of the invention is a process for the synthesis of nitrides 4d and 5d of transition metals (Nb, Mo Ta, W) in the form of quasi-one-dimensional structures, i.e. nanoparticles, microsounds, nanotubes and microtears. The invention comprises the synthesis of nitrides of transition metals in the form of quasi-one-dimensional structures with the method of converting quasi-one-dimensional compounds with a submicro cross section of the nanoparticles described by the formula M6CyHz, 8.2 smaller than y + z less than 10, where M is a transition metal (Nb, Mp Ta, W ), C is a chalcogen (sulfur (S), selenium (Se), telur (Te)); H is halogen (iodine (I)) by heating in the presence of ammonia. This process allows the synthesis of large amounts of nitrides 4d and 5d (Nb, Mo Ta, W) of transitional metals in the form of quasi-one-dimensional structures (nanoscale, microsounds, nanotubes and microtrains).
