Abstract

Ultra-fine, nano-crystalline six-line ferrihydrite (5Fe₂O₃·9H₂O) and cubic zirconia (ZrO₂) powders have been produced using the Rapid Thermal Decomposition of precursors in Solution (RTDS) technology. Nano-crystalline RTDS six-line ferrihydrite powder used as an in situ precursor for first-stage direct coal liquefaction catalysts increased the liquefied products from Blind Canyon Seam coal by 22% absolute over thermal background at 350 °C. Initial sintering studies performed on nano-crystalline RTDS ZrO₂ powder have also been presented and compared to predictions made from theories derived for micro-crystalline powders.
