Kinetics and thermodynamic parameters for the manufacturing of anhydrous zirconium tetrafluoride with ammonium acid fluoride as fluorinating agent

Pretorius, C.J.; Du Plessis, W.; Nel, Johannes T.; Crouse, Philippus L. (Southern African Institute of Mining and Metallurgy, 2012-07)

More than 30 percent of the global demand for zircon (ZrSiO4) is supplied by South Africa. A significant amount of the zircon is exported, and beneficiated products are then imported for industrial applications locally. ...
Treatment of TRISO-coated particles with CF4 in a low temperature plasma

Van der Walt, Izak Jacobus; Nel, Johannes T.; Crouse, Philippus L.; Jansen, Arnold Alexander; Kekana, Sipho J. (Elsevier, 2011-06)

An alternative recovery method to the mechanical crushing of off-specification tri-structural-isotropic (TRISO) coated fuel microspheres is demonstrated. It is shown that the inert SiC layer can be completely removed by ...
