Definitions

  • Rotation of the reaction chamber is necessary to decrease the diffusion limit having a key role in kinetics of reaction, but at the same time, as mentioned above, the reaction products, due to the effect of the centrifugal force, form a sediment on a surface placed in the direction of the centrifugal force.
  • FIG. 1 A particular embodiment of the apparatus according to the present invention is shown in Fig. 1 .
  • the apparatus is suitable for producing titanate nanostructures by means of alkali-hydrothermal process starting from titanium containing base material.
  • the apparatus contains at least a vessel 1 to be closed by a closure cap F and said vessel 1 is rotatable around an axis T.
  • the vessel 1 is preferably cylindrical and the centreline k of said axis T is the axis of symmetry of the vessel 1.
  • the closure cap F is fitted to the vessel 1 by means of a thread, and it is secured against rotation to an inner cap 4 by means of clamping screws.
  • the closure cap F may be formed and secured by means of other known solutions, indeed.
  • Vessel 1 is a cylindrical container in the embodiment shown, having a shell 5, and a coating 2 is arranged on the inner surface thereof.
  • Mixing devices 3 are arranged inside the vessel (1), which are independent of the structure of the vessel 1 and freely movable inside the vessel 1.
