Introduction of observations on large sponge titanium and small sponge titanium.

The sponge titanium small was classified into processed and unprocessed products, and the differences in surface conditions were observed using a scanning electron microscope (SEM) at varying magnifications. [BET Method] ■ Sponge Titanium Large - BET specific surface area 5.4203 m²/g micropore (pore diameter less than 40 angstroms) - BET specific surface area 4.1314 m²/g macropore (pore diameter between 40 and 360 angstroms) ■ Sponge Titanium Small - BET specific surface area 3.3912 m²/g micropore (pore diameter less than 40 angstroms) - BET specific surface area 2.5581 m²/g macropore (pore diameter between 40 and 360 angstroms) [SEM Observation of Sponge Titanium Surface] Please refer to the PDF document for SEM observation photos. *For additional details, please download and view the PDF.

basic information

What is the photocatalyst "Titanistar"? It is not a coating-type photocatalyst, nor does it use any of the raw materials employed in those types. By simply performing surface oxidation treatment on titanium within pure titanium metal, a titanium dioxide photocatalyst film is generated on the surface of pure titanium. This film contains no impurities and is generated without any interface with pure titanium. It is characterized by high photocatalytic ability and a highly durable film. What the photocatalyst "Titanistar" can solve: - Water purification and water quality improvement, although it is not suitable for purifying highly contaminated water. - Gas purification and air cleaning. - General bacteria and various virus countermeasures. Discussion: It has been found that the specific surface area of sponge titanium large and sponge titanium small, measured by the BET method, has a certain area. Additionally, surface observation using SEM revealed that a porous film is generated through Titanistar treatment. These findings indicate that the application of sponge titanium Titanistar can be expanded regardless of whether it is in gas or liquid phase. *For more details, please refer to the PDF materials or feel free to contact us.*
