International Journal of Refractory Metals and Hard Materials, 1995 Abstract Tungsten blue oxide (TBO), currently the most important highly pure intermediate for reduction to tungsten metal powder, is described from various viewpoints, such as chemical composition, physical constitution and homogeneity. Tungsten blue oxide is not a well defined product, with varying chemical and physical properties which depend on ...

OXIDATION OF TUNGSTEN AND TUNGSTEN BASED ALLOYS [PDF]
, 1961 Abstract : The results of studies related to the oxidation of W and its alloys are studied. The pressure of WO3 polymers over WO2 was measured in a W Knudsen cell and found to agree with measurements in a Pt cell. Literature data for WO2 WO3 were combined with vapor pressures determined in this project to give thermodynamic values for W18O49 and W20O58.
