The role of carbon nanotubes and cobalt in the synthesis of pellets of titanium silicates

In the present work self-bonded pellets of Engelhard Titaniun Silicates, ETS-4 and ETS-10, containing cobalt and carbon nanotubes, were synthesized by hydrothermal synthesis at 190 A degrees C, from gels of the initial composition x-Na2O-0.2TiO(2)-0.6KF-(1.28x - 2y)HCl-2yHNO(3)-1.49SiO(2)-yCoO-39.5H(2)O, with x equal to 0.8; 1; 1.5; 2.5 mol and y equal to 0.015; 0.03; 0.06; 0.1. To the initial gels were then added different weight percentages of carbon nanotubes compared to the dry gel. The obtained pellets were characterized by X-ray diffraction analysis, thermal analysis (TG, DTG, DSC), tests of mechanical resistance to compression and nuclear magnetic resonance.
