A simple, low-cost and an eco-friendly synthesis of Ir-doped titanium dioxide nanoparticles (TiO2 NPs) with an anatase phase by the microwave-assisted method using an aqueous solution of titanium tetra-isopropoxide (TTIP) and iridium (III) chloride monohydrate.<span class="CharOverride...

fluoride-containing solutien. Commercially pure titanium (CP-Ti) and six titanium-based alloys were used: Ti-O.15Pd, Ti6Al-4V, Ti-7Nb-6Al, Ti-55Ni, Ti-10Cu, and Ti-20Cr. Two test solutions were prepared fbr immersion of polished titanium and titanium alloys: one consisting of O,2% NaF + O,9% NaCl (pH 3.8 with lactic acid) and the other of O.1 mol/1 H202 + O.9% NaCl (pH 5.5). Following immersion...

The microstructure, mechanical properties, and corrosion behavior of binary Ti-xPt alloys containing 5, 10, 15 and 20 wt% Pt were investigated in order to develop new Ti-based dental materials possessing superior properties than those of commercially pure titanium (cp-Ti). All of the Ti-xPt (x = 5, 10, 15, 20) alloys showed hexagonal α-Ti structure with cubic Ti₃Pt intermetallic phase. The mech...

The reactions of mono(cyclopentadienyl)titanium(IV) trichloride and bis(cyclopentadienyl)titanium(IV)/ zirconium(IV) dichloride with a new class of dithiosemicarbazone, derived by condensing piperazine dithiosemicarbazide with benzaldehyde (L(1)H(2)), 2-chlorobenzaldehyde (L(2)H(2)), 4-nitrobenzaldehyde (L(3)H(2)) or salicylaldehyde (L(4)H(4)) have been studied and different types of binuclear ...

The present study was undertaken to evaluate the clinical applicability of cast CP titanium crowns fabricated with sintered molds. To this end, the dimensional changes and accuracy of fit of cast CP titanium crowns, manufactured under varying mold firing temperatures, were examined. Molds were fired at 7 temperatures. The outer height of the crown and outer width of the occlusal surface decreas...

It is not known for certain that dental stone components influence titanium welding. In this study, we investigated metallurgical problems caused by laser welding on dental stones using wrought commercial pure (CP) titanium. A pulsed Nd:YAG laser irradiated a number of specimens' surfaces which were fixed on either a dental hard stone or a titanium plate. The metallurgical properties of the wel...

The aim of the present study was to evaluate the dimensional accuracy and surface property of titanium casting obtained using a gypsum-bonded alumina investment. The experimental gypsum-bonded alumina investment with 20 mass% gypsum content mixed with 2 mass% potassium sulfate was used for five cp titanium castings and three Cu-Zn alloy castings. The accuracy, surface roughness (Ra), and reacti...

The aim of the work was to evaluate the influence of the temperature of investment healting on the tensile strength and Vickers hardness of CP Ti and Ti-6Al-4V alloy casting. Were obtained for the tensile strength test dumbbell rods that were invested in the Rematitan Plus investment and casting in the Discovery machine cast. Thirty specimens were obtained, fifteen to the CP Titanium and fiftee...
