Facile preparation of dual La-Zr modified magnetite adsorbents for efficient and selective phosphorus recovery

, 2020
Phosphate (P) is an irreplaceable resource for the growth of all living organisms, and the impending exhaustion of minable P rock arouses the demand of P recovery, which further promotes the novel technologies development.

Anisotropic corrosion behavior of Sc and Zr modified Al-Mg alloy produced by selective laser melting

, 2020
Electrochemical measurements and microstructural analyses were conducted to investigate the corrosion behaviors on different planes of Sc and Zr modified Al-Mg alloy produced by selective laser melting (SLM). Results indicated that the XY-plane exhibited

Zr/Mg, Zr/Sr and Zr/Zn co-doped hydroxyapatites: Synthesis and characterization

Ceramics International, 2016
Abstract Zr/Mg, Zr/Sr and Zr/Zn co-doped hydroxyapatite samples, having high crystallinity, prepared by sol–gel synthesis were characterized via X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) spectroscopy. Based on the XRD results, it is shown that the kind

Advanced applications of Zr-based MOFs in the removal of water pollutants.

Chemosphere, 2020
The global water pollution is caused by the increase of industrial and agricultural activities, which have produced various toxic pollutants. Pollutants in water generally consist of metal ions, pharmaceuticals and personal care products (PPCPs), oil ...

INVESTIGATION OF Zr-ZrN, Zr,Hf-(Zr,Hf)N AND Zr,Nb-(Zr,Nb)N COATINGS DEPOSITED ON A TITANIUM ALLOY SUBSTRATE

High Temperature Material Processes An International Quarterly of High-Technology Plasma Processes
The properties of Zr-ZrN, Zr,Hf-(Zr,Hf)N and Zr,Nb-(Zr,Nb)N coatings deposited on a Ti6Al-4V titanium alloy substrate were studied. It has been established that the introduction of hafnium increases, and niobium reduces the hardness of the coating. The introduction of hafnium also increases, and niobium reduces, the value of the critical fracture load ...

On the Stability and Structure of Zr-Cu and Zr-Ti-Cu Alloys

Solid State Phenomena, 1998
The alloys Zr-Cu-Ti and Zr-Cu have been prepared by melt-spinning and mechanical alloying techniques. Their thermal behaviour and structure factors have been investigated. Thermal properties obtained by differential scanning calorimetry, of an amorphous alloy (54Zr34Cu10Ti), were tested in argon and nitrogen atmospheres.

Effects of minor rare earths on the microstructure and properties of Cu-Cr-Zr alloy

, 2020
The effects of minor rare earths, such as Sc, Er, and Y, on the microstructure and properties of Cu-Cr-Zr alloys, were studied systematically. Microstructure evolutions and properties variations of Cu-Cr-Zr-(X) alloys indicate that the hot-rolling ...

Contribution to the Zr-rich part of the Zn-Zr phase diagram

Journal of Phase Equilibria and Diffusion, 2004
The reaction of zinc vapor with Zircaloy-4 and nuclear grade zirconium was investigated with various analytical techniques: optical metallography, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Based on the results, the Zr-rich part of the Zn-Zr phase diagram was revised. A eutectoid decomposition of (βZr) occurs at 718±

Low-Temperature Specific Heats of Zr-Ti, Zr-Hf, and Zr-Sc Alloys

Physical Review, 1968
The specific heats of hexagonal Zr-Ti, Zr-Hf, and Zr-Sc alloys were measured at 1.1 to 4.2\ifmmode^\circ\else\textdegree\fi{}K. Maxima in both the electronic specific-heat coefficient $\ensuremath{\gamma}$ and the superconducting transition temperature ${T}_{c}$ were observed at 60 at.% Ti in the Zr-Ti system.
