The effect of zinc phosphate (ZP) and zinc calcium phosphate (ZCP) coatings on the reinforcing mechanisms of smooth steel fiber in cementitious matrix have been studied. The results of pull out tests illustrated that by coating smooth steel fiber the pull-out load may be increased up to 100%. The effect of zinc phosphate coating on interface bonding was more than zinc-calcium phosphate coating....

In this article, the effect of potassium on structure and anticorrosion properties of zinc phosphate pigments has been investigated. The co-precipitation method was selected as synthesis method of potassium zinc phosphate pigment. Then the synthesized pigment was characterized by x-ray diffraction XRD, Fourier transform infrared FTIR and Raman spectroscopy. Morphology of the powders was investi...

BACKGROUND Continuous dialysis could provide benefit by constant removal of potassium and phosphate. This study investigates the suitability of specific potassium and phosphate sorbents for incorporation in an extracorporeal device by capacity and regenerability testing. METHODS Capacity testing was performed in uraemic plasma. Regenerability was tested for potassium sorbents, with adsorption...

Film thickness, strength, solubility and microleakage of dental cements are essential factors in cement selection by dentist. Since failure of metal ceramic restorations is mostly due to their marginal leakage and provious studies have shown that microleakage of Resin, Glassionomer and Zincphosphate cements are different, this study was done to compare the rate of microleakage between Ariadent ...

The effects of using different promoters on hydrotalcite based cobalt (HT-Co) catalyst for FischerTropsch Synthesis was studied in this paper. The HT-Co catalysts were synthesized by using hydrothermal method whereas zinc and zirconium were added separately as promoters, by wetness impregnation method. The main aim of the study is to see the difference in properties of both zinc and zirconium p...

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...

Nanocomposite of ZrO2/ZnO was prepared under ultrasonic irradiation by sol gel process from directly mixing Zirconium and Zinc gels, and the mixture was placed under ultrasonic irradiation for 2 hours then aging time the filtrated composite gel was calcinated at 500°C for 3h in furnace. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4 and zinc acetate dihydrated was...

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