This article focuses on the galvanic replacement synthesis of Ti-Ni and Zr-Ni metal systems with a “core-shell” structure, which are potential precursors for intermetallics. The authors defined effective parameters formation features polymetallic characterized by granulometric, phase, elemental composition. X-ray fluorescence phase analysis methods showed that deposition nickel dispersed titani...

In this paper, we report the preparation of nickel phosphate in aqueous solution and its use as inorganic pigment. Because cerium phosphate is insoluble in acidic and basic solution, the addition of cerium was tried to improve the acid and base resistance of nickel phosphate pigment. The cerium substituted nickel phosphates were prepared from phosphoric acid, nickel nitrate, and ammonium cerium...

In this paper, a novel Ni2P/black phosphorus (Ni2P/BP) supported on two-dimensional ?-zirconium phosphate (?-ZrP) hybrid material was prepared, and its catalytic activity for hydrodesulfurization (HDS) investigated. Through the reaction of nickel salt with BP nanosheets obtained by freeze-assisted exfoliation method, Ni2P nanoparticles can be formed firmly anchored surface BP, effectively preve...

Lithium exchanged phases of amorphous and crystalline zirconium titanium phosphate have been synthesized by an ion exchange technique. These materials have been characterized by elemental analysis (ICP-AES and AAS), spectral analysis (FTIR), thermal analysis (TGA) and X-ray diffraction studies. The conductance properties of these materials have been explored by measuring specific conductance at...

A series of montmorillonite-(Ce or Zr) phosphate crosslinked compounds has been synthesized by reaction of a cerium or zirconium cation exchanged montmorillonite (diameter ~2 pm) with phosphoric acid under appropriate conditions of concentration, addition rate and temperature. The materials thus obtained were characterized by chemical and thermal analyses, X-ray diffraction, IR spectroscopy and...

A co-impregnation method was applied to the Ni/Zr-HMS/HZSM-5 catalyst (with various amounts of zirconium) during the hydrogenation of benzene. The physicochemical properties of the prepared nickel catalyst were characterized using X - ray diffraction, X - ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed desor...

Zirconium phosphate is able to intercalate basic molecules and it an effective drug carrier that can be used project slow release for topical applications.

The influence of precipitation of intermetallics on changes in Young’s modulus of nickel and zirconium base alloys has been discussed in this paper. This study indicates that the change in the modulus due to thermal ageing in these alloys is essentially governed by the change in the modulus of the matrix due to removal of precipitation forming elements. 1.0 Introduction Mechanical properties in...
