The biocompatible lattice structures and implants disclosed herein have an increased or optimized lucency, even when constructed from a metallic material. The lattice structures can also provide an increased or optimized lucency in a material that is not generally considered to be radiolucent. Lucency can include disparity, maximum variation in lucency properties across a structure, or dispersion, minimum variation in lucency properties across a structure. The implants and lattice structures disclosed herein may be optimized for disparity or dispersion in any desired direction. A desired direction with respect to lucency can include the anticipated x-ray viewing direction of an implant in the expected implantation orientation.

To provide a titanium-based porous body that has high void fraction to ensure gas permeability and water permeability for practical use as an electrode and a filter, has a large specific surface area to ensure conductivity and sufficient reaction sites with a reaction solution or a reaction gas, thus showing excellent reaction efficiency, and contains less contaminants because of no organic substance used. A titanium-based porous body having a specific void fraction and a high specific surface area is obtained by filling an irregular-shaped titanium powder having an average particle size of 10 to 50 μm in a dry system without using any binder or the like into a thickness of 4.0×10.sup.−1 to 1.6 mm, and sintering the irregular-shaped titanium powder at 800 to 1100° C.

The present disclosure provides a preparation method of a metal powder material. An alloy sheet composed of a matrix phase and a dispersive phase with different chemical reactivities is prepared by the rapid solidification technique of alloy melt. Metal powder is prepared by the reaction of the alloy sheet and an acid solution. Please refer to the description for the detailed preparation method. This method is simple in operation, can be used to prepare many kinds of metal powder materials of different shapes and at the nanometer scale, the submicron scale and the micron scale, and has a good application prospect in the fields of catalysis, powder metallurgy and 3D printing.
