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...

Titanium is one of the most utilized metals for orthopedic implants. This element has excellent mechanical and biological properties. As a strategy to develop new system alloys that do not cause health problems patient, such as Ti-6Al-4V alloy, group been designed meet these expectations. Molybdenum, when associated with titanium, reduces transition temperature from α β phase. Zirconium increas...

Nucleation and growth of zirconium-oxo-alkoxy (ZOA) nanoparticles were studied in a sol-gel process in n-propanol solution at a hydrolysis ratio H between 1.0 and 2.7 and zirconium-n-propoxyde precursor concentrations between 0.10 and 0.15 mol l(-1). The chemical transformations were conducted in quasi-perfect micromixing conditions (Damköhler number Da ≤ 1) and the nanoparticle size evolution ...

Effect of ageing on the mechanical properties of Al-6Mg alloy doped with 0.4 wt% scandium and with or without trace zirconium and titanium is studied. As cast, samples were aged isochronally for 60 minutes at different temperatures up to 500C. The evaluation of tensile properties of the aged Al-6Mg (Sc, Zr, Ti) alloys was conducted by employing an Instron testing machine. Various strain rate of...

Objective. The present study assessed the chemical elements in two novel calcium silicate-containing root canal sealers, BioRoot RCS and Well-Root ST, compared to a calcium silicate-containing root canal sealer that has been on the market for several years, MTA Fillapex, and epoxy resin-based sealer AHPlus. Material and Methods. The sealers were mixed and manipulated according to the manufactur...

Dental implants made from binary titanium-zirconium (TiZr) alloys have shown promise as a high strength, yet biocompatible alternative to pure titanium, particularly for applications requiring small diameter implants. The aim of this review is to summarize existing literature reporting on the use of binary TiZr alloys for endosseous dental implant applications as tested in vitro, in animals and...

Background And Objective:Dental implants have been universally accepted as the best option for prosthetic rehabilitation of missing teeth.A material choice manufacturing dental was long time commercially pure titanium due to its excellent bio compatibility and mechanical properties. Zirconia seems be a suitable alternative implant because tooth like color biocompatibility. The most promising no...

An advanced inorganic material of the class of tetravalent bimetallic acid (TBMA) salt zirconium titanium phosphate (ZTP) has been synthesized by sol gel route. ZTP has been characterized for elemental analysis by ICP-AES, FTIR, TGA and X-ray diffraction studies. Ion exchange capacity (IEC) of material was determined and effect of calcination (373-773 K) on IEC studied. Chemical resistivity of ...
