Abstract: The present invention prescribes a new sol-gel method of preparing and formation of the metal oxide microtubes. According to the method firstly is prepared the precursor sol from metal oxides or mixtures of metal oxides and alkoxides, thereafter from the precursor sol are extruded the fibres, which are gelatinised afterwards until the inner sol which is less viscous of fibres is converted to thinner wall until alcohol from the precursor is left trough walls. The metal oxide microtubes are applicable as to conduct liquids or gasses, as ionic conductors, as catalyst carriers and as light emitters.
