Production of nuclear grade zirconium: A review

Abstract. Zirconium is an ideal material for nuclear reactors due to its low absorption cross-section for thermal neutrons, whereas the typically contained hafnium with strong neutron-absorption is very harmful for zirconium as a fuel cladding material. This paper provides an overview of the processes for nuclear grade zirconium production with

Zirconia an overview ScienceDirect Topics

Zirconia. Zirconia is a polymorphic material occurring in three temperature-dependent forms: monoclinic or baddeleyte (room temperature to 1170°C), tetragonal (1170–2370°C) and cubic (2370–2700°C, which corresponds to the melting point). From: Acta Biomaterialia, 2013. Download as PDF.
