or g solid solutions 268, 845. nanotubes are less than 10 nm in diameter and they are 33 arranged in bundles several tens of micrometers long Starting from an a-solid solution, the increase in reduction Symp 359, 241. temperature from 900 to 1000 °C produces an increase in the 35 supersaturation level in the reduction atmosphere. However, a 36, these powders, Nature amount of nanotubes, probably owing to the higher CH, pp.381-678, 1994. ,
