PREPARATION OF ZIRCONIUM FROM ZIRCONIUM TETRAFLUORIDE
, 1957 Increased interest in zirconium as a material of construction has resulted in numerous attempts to develop more economical processes for its production. Currently the Kroll Process, which reduces zirconium tetrachloride with magnesium, is used. A process developed at the Ames Laboratory of the Atomic Energy Commission involves the bomb reduction of ...

EXAFS Study of Zirconium Monobutylphosphate and Zirconium Dibutylphosphate [PDF]
Journal of Nuclear Science and Technology, 1990 EXAFS (Extended X-ray Absorption Fine Structure) measurement was carried out for the study of the local structure around Zr in precipitates of Zr (IV) -monobutylphosphate and Zr (IV)-dibutylphosphate, which are one of the main species of so-called “The Third Phase”.
