Studies on the rates of reaction between molybdenum trioxide vapour and solid niobium pentoxides

The rates of reaction between solid HNb2O5 and TiNb24O62 and MoO3 vapour have been studied at 800 and 900°C with a simple gravimetric technique. Block compounds of the structure types WNb12O33 and W3Nb14O44 were formed rapidly. Reaction mechanisms are discussed. Die Geschwindigkeit der Reaktion von HNb2O5 und TiNb24O62 mit MoO3-Dampf wurde bei 800 und 900°C mit einer einfachen Wagetechnik untersucht. Hierbei entstehen schnell Verbindungen vom Typ der Blockstrukturen WNb12O33 und W3Nb14O44. Reaktionsmechanismen werden diskutiert.
