Influence of OH- concentration on the illitization of kaolinite at high pressure
(Elsevier, 2011)
The products of hydrothermal reactions of kaolinite at 300°C and 1000 bars were studied in KOH solutions covering an OH- concentration, [OH-], of 1M to 3.5M. XRD patterns indicated a notable influence of the [OH-] on the ...

Blocking of grain reorientation in self-doped alumina materials
(Elsevier, 2011)
Alumina nanoparticles 10–20 nm in diameter were nucleated on alumina particles, 150 nm average diameter, by a colloidal route followed by calcination. It is shown that after sintering, the final grain size is up to 20% ...
