Influences of sintering temperature on pore morphology, porosity, and mechanical behavior of porous Ti

Porous Microneedles for Therapy and Diagnosis: Fabrication and Challenges

“…Experiments found that sintering was conducted at four temperatures of 900, 1000, 1100, and 1200 °C and found that with the gradual increase of temperature, the porosity decreased from 56.48% to 46.83%, and the pore size also gradually decreased, while the initial yield strength of porous titanium increased from 101.81 to 208.01 MPa. 57 Another study also came to a similar conclusion; 58 as the sintering temperature increased from 1000 to 1300 °C, the formed porous titanium pore shape became rounded, the number of micropores decreased, and the mechanical properties increased. Finally, because fast heating rates cause sample deformation during debinding and sintering, a slower heating rate is typically used for debinding and sintering.…”

“…When it comes to sintering temperature, the higher the temperature, the smaller the pore size and porosity of the product, and the higher the mechanical properties.
