Ultra-fine, nano-crystalline six-line ferrihydrite (5Fe{sub 2}O{sub 3}9H{sub 2}O) and cubic zirconia (ZrO{sub 2}) 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{degrees}C. Initial sintering studies performed on nano- crystalline RTDS ZrO{sub 2} powder have also been presented and compared to predictions made from theories derived for micro- crystalline powders.
