Preparation of Thoria and Mixed-Oxide Microspheres

Preparation of Porous Thoria by Incorporation of Carbon in Sols.

“…their specific surface areas to decrease to 13,17,17,10, and 81 m /g respectively. These areas are still quite high in view of the thermal treatment.…”

Laboratory and Engineering Studies of Sol--Gel Processes at Oak Ridge National Laboratory.

“…The initial development of the process for the preparation of Tho2 microspheres and i t s application to U 0 2 or U02-Zr02 sols have been previously reported, 16,17 Our work has included the operation of a microsphere pilot plant, with procedures and equipment required for a remote facility, the application of the process to a variety of sols on a larger scale, and the continued development of dispersers for sols.…”

An Improved Oil Emulsion Synthesis Method for Large, Porous Zirconia Particles for Packed- or Fluidized-Bed Protein Chromatography

“…Harris et al (7) used a reactive dispersion process to form pure and mixed oxide ceramic particles from aqueous salt solutions. Various emulsifying techniques have been used including stirrers (4), two-fluid nozzles (5, 6), vibrating capillaries (5,6), and pulsing electric fields (7).…”
