Spherical titanium powder, a metal powder with unique morphology and excellent properties, has attracted widespread attention in materials science and engineering in recent years. Due to its approximate spherical shape, this titanium powder has good flowability, filling ability, and plasticity, enabling it to fill molds better and improve production efficiency during manufacturing. In addition, the surface of spherical titanium powder is smooth, has high purity and activity, and can undergo rapid reactions.
Characteristics of Spherical Titanium Powder
Morphology and physical properties: The shape of spherical titanium powder is approximately spherical, with a smooth surface and high purity. Its particle size is small, and its particle size distribution is narrow, with good fluidity. In addition, its high density and high activity enable it to fill the mold during the manufacturing process better, improving the density and performance of the product.
Chemical properties: Spherical titanium powder has high corrosion resistance and good biocompatibility, making it widely applicable in the biomedical field. In addition, its excellent catalytic performance has potential application value in the chemical industry.
Preparation method of spherical titanium powder
The preparation methods of spherical titanium powder mainly include physical and chemical processes. The following are two main preparation methods:
Physical method: The physical method mainly includes mechanical ball milling and vapor deposition methods. The automated ball milling method involves mixing titanium powder with a grinding ball and gradually approaching the spherical shape of titanium powder through the friction effect of the ball mill. The principle of vapor deposition is to use physical processes to deposit titanium atoms onto a substrate to form spherical titanium powder.
Chemical method: The chemical method mainly includes hydrothermal synthesis and vapor deposition methods. The hydrothermal synthesis method is the reaction of titanium salts with other substances under high temperatures and pressure to generate spherical titanium powder. The chemical vapor deposition principle uses chemical reactions to deposit titanium atoms onto the substrate to form spherical titanium powder.
