A porous open-framework titanium oxophenylphosphate

Journal of Solid State Chemistry, 2008
Abstract Highly porous titanium oxophenylphosphate (TPP-1) has been synthesized hydrothermally at 448 K using phenylphosphonic acid (PPA) as the organophosphorus source without the aid of any template or structure-directing agent (SDA). Powder XRD, TEM, SEM-EDS, N 2 sorption, ICP-AES chemical analysis, 13 C and 31 P MAS NMR, UV–Vis, XPS ...

Synthesis of porous titanium dioxide membranes

Desalination, 2007
Abstract Until recently, the industrial membranes used for filtration, distillation, separation or extraction were manufactured from polymers. However, inorganic membranes are emerging as an alternative to polymeric membranes for applications due to their thermal, mechanical and chemical characteristics.

Heat transfer performance of porous titanium

Journal of Iron and Steel Research International, 2017
Porous titanium fibre materials with different structural parameters were prepared by vacuum sintering method. The thickness, porosity and wire diameter of prepared materials were investigated to understand the effects of structural parameters on pool heat transmission performance of titanium fibre porous material.

Porous Titanium for Medical Implants

Multidisciplinary Materials Chronicles
Porous titanium and its alloys have shown immense promise as orthopedic and dental implant materials owing to their outstanding properties, namely tailorable porosity, the ability of blood vessels and bone ingrowth, the transport of nutrients and/or biofluids, and vascularization.

Understanding compressive deformation in porous titanium

Philosophical Magazine, 2010
The aim of this study was to understand and compare the compression deformation behavior of porous metals with random and designed porosity. Direct observation, analysis and quantification of porosity parameters using microcomputed tomography (µCT) enabled the determination of relationship between porosity characteristics and compressive deformation of

Osteointegrated porous-coated titanium implants.

La Chirurgia degli organi di movimento, 1995
The study deals with the bone-prosthesis interface using an in vivo experimental animal model in relation to loading and walking on the prosthetized hip, studied by force plate analysis. The interface is studied from a histological and morphometric point of view by means of a LECO 2001 system.

Porous titanium obtained by P/M

Le Journal de Physique IV, 2001
Porous materials are needed for the development of new surgical implants where reliable implant-to-bone fixation is accomplished. Here we report a method based an P/M technology to obtain titanium alloys with controlled porosity and good mechanical properties due to the use of nanocrystalline powders, with means of the traditional sintering techniques ...

A lanthanum titanium porous glass ceramic

Journal of Materials Science, 1983
Studies on the substitution of the end-member oxides in the ternary sodium borosilicate system have included work on the replacement of SiO2 with combinations of La2O3 and TiO2 which after heat treatment resulted in leachable sodium borate and insoluble La2O3-TiO2 ceramic phases.

[Titanium porous-surface screw implant].

Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 1996
Titanium porous-surfaced screw implant was made by plasma-spray with Ti powder. The pore size was 80-300 microns. Two groups of implants were implanted in the mandibles of 15 dogs. Group A: porous-surfaced screw implant: Group B: smooth surface screw implant. The bone healing was evaluated by L. M. SEM. and shear strength testing. The results show that

Combustion synthesis of porous titanium microspheres

Materials Chemistry and Physics, 2013
Abstract The synthesis of titanium porous microspheres by a combustion technique was studied under an argon atmosphere by using a TiO 2  − 2.5Mg reactive mixture. The precursor, a fine TiO 2 powder, was thermally treated in the range 600–1300 °C prior to the combustion experiments.
