Results are provided for a study of the effect of preparation conditions on the structural properties of dispersed systems based on potassium polytitanates. It is established that on heating there are complex structural transformations within polytitanates, and the composition of modifying surface-active substances (SAS) has a specific effect on microstructure formation and the final morphology of polytitanate particles. Temperature regimes are determined making it possible with use of non-iogenic SAS to prepare nanostructured powder materials consisting of uniform fiber particles less than 10 nm thick, 30 - 50 nm wide, and 2 - 5 μm long. © 2012 Springer Science+Business Media, Inc.

Refractories and Industrial Ceramics | Year: 2012

The possibility is demonstrated of a considerable improvement in mechanical properties of vibration-cast refractory objects by introducing nanosize fractions into thixotropic mullite-corundum mixes. It is established that the efficiency of using nano-additions is governed by its introduction technology into refractory material. The best method is mixing in vortex layer equipment with use of a high-intensity rotating magnetic field. © 2012 Springer Science+Business Media, Inc. Source
