Zirconium(4+), denoted as Zr4+, is a chemical species of zirconium in which the metal has lost four electrons, resulting in a +4 oxidation state. Zirconium is a transition metal belonging to the lanthanide series, and it is characterized by its high melting point, resistance to corrosion, and excellent mechanical properties. In its 4+ state, zirconium forms various compounds, such as zirconium dioxide (ZrO2) and zirconium tetrachloride (ZrCl4), which have applications in various industries, including nuclear reactors, ceramics, and chemical catalysts. Zirconium(4+) is also known for its low neutron absorption cross-section, making it a valuable material in nuclear engineering.

15543-40-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 15543-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 15543-40:
(7*1)+(6*5)+(5*5)+(4*4)+(3*3)+(2*4)+(1*0)=95
95 % 10 = 5
So 15543-40-5 is a valid CAS Registry Number.

Order—Disorder transformation and its effect on the properties of (Lanthanide)2Zr1.5Hf0.5O7 functional nanoceramics

Rejith,Thomas, Jijimon K.,Solomon, Sam

, p. 1 - 11 (2019)

Order disorder transformations and its effect on the structural, optical and ionic transport properties of the cubic pyrochlore – defect fluorite structures are the prime focus of this study. Nanoceramics of Ln2Zr1.5Hf0.5O7 (Ln = Pr, Nd, Sm, Gd, Dy and Er) are prepared through the modified combustion technique. X – ray diffraction analysis and electron microscopic studies show the cubic nano crystallite nature of the materials. Vibrational studies reveal the pyrochlore–fluorite phase transformation in the series. Highly dense bulk ceramics are prepared from the nano particles at relatively low temperatures. The gradual replacement of Ln3+ ions in Ln2Zr1.5Hf0.5O7 changes the pyrochlores (Ln = Pr-Sm) to defect fluorite (Ln = Er) through the weakly ordered defect fluorites (Ln = Gd and Dy). Impedance spectroscopic analysis carried on the bulk ceramics shows the influence of phase transformation on the oxide ion conduction of bulk materials. The peak oxide ion conduction is observed for the Ln = Dy ceramic, which is at the pyrochlore fluorite phase boundary.

Zirconium sorption by chelating polymer sorbents with an o,o′-dihydroxyazo analytical functional group

Basargin,Oskotskaya,Simakov,Rozovskii

, p. 1972 - 1976 (2008)

The complexing properties of new chelating polymer sorbents (CPSs) with an o,o′-dihydroxyazo functionality and zirconium sorption on these sorbents were studied. Quantitative correlations were found between pK′ OH of the analytical functional g
