Tailoring the Porous Hierarchy of Titanium Phosphates
Langmuir, 2006First hierarchical titanium phosphate (TiPO) materials with multiple porosities of different lengths (meso-macroporous and meso-macro-macroporous) were synthesized by the self-formation process. The further tuning of the porous hierarchy by using the poly(ethylene oxide) surfactant technique was demonstrated.

Direct calciothermic reduction of porous calcium titanate to porous titanium
Materials Science and Engineering: C, 2018A metallurgical material integration concept, using porous calcium titanate (CaTiO3) as raw material, was put forward for preparation of metallic titanium powder and porous titanium by calciothermic reduction. Porous metallic titanium was prepared by calcium vapor reduction at 1273 K for 6 h with two types of interconnected pores in titanium samples ...

Porous Titanium Implants: A Review
Advanced Engineering Materials, 2018Titanium and its alloys are commonly used in almost all disciplines of medicine because of their sufficient biocompatibility and meeting of mechanical requirements. However, dense metallic biomaterials represent only an interfacial connection with host tissue, may develop stress shielding which causes ingrowth of the fibrous tissue, and are prone to ...

Porous titanium dental implants
Journal of Biomedical Materials Research, 1974AbstractTitanium implants have been designed which utilize a solid core and porous exterior. The technique for implants containing posts utilizes a cast chromium‐cobalt splint for fixation and the buried implants are held in place by the overlying gingiva until tissue growth into the porosity results in stabilization.Clinically successful post implants

Tubular macro-porous titanium membranes
Journal of Membrane Science, 2014Abstract We present tubular macroporous titanium membranes prepared via a dry-wet spinning process from a polyethersulfone solution loaded with Ti particles (15 μm) and a subsequent sintering process at various sintering temperatures (1100–1500 °C) and sintering times (30–75 min).

Porous titanium surgical implant materials
Journal of Biomedical Materials Research, 1971AbstractPorous pure titanium and titanium‐6% aluminum‐4% vanadium alloy materials, made by several powder metallurgy techniques, have been studied for potential use as surgical implant materials. Tissue ingrowth into open porosity and favorable physical properties have been found.

Hybrid solid-porous titanium scaffolds
2019The aim of this study was to fabricate by selective laser melting hybrid solid-porous titanium scaffolds with regions of different porosities (500, 700 and 900 µm) controlled by the size of the diamond structure. In order to remove unmelted powder particles, obtain the required surface finish and render CAD model dimensions fabricated structures were ...

Highly porous titanium scaffolds for orthopaedic applications
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2010AbstractFor many years, the solid metals and their alloys have been widely used for fabrication of the implants replacing hard human tissues or their functions. To improve fixation of solid implants to the surrounding bone tissues, the materials with porous structures have been introduced. By tissue ingrowing into a porous structure of metallic implant,
