Abstract:

Single crystals of hematite Fe2O3 grown from Na2B4O7 occur as plates, rods, hoppers, and equidimensional solid crystals. The habit was found to correlate with the growth rate and crystal defects. Plates and rods occurred for the highest growth rates used with the plate size controlled by rapid growth perpendicular to the 0001. The rods are the result of twinning on the 0,1,01,2. The hoppers and solid crystals grow in slow-cooled melts and are typical of crystals grown from high-viscosity melts. Author
