The biological activity, biocompatibility, and corrosion resistance of implants depend primarily on titanium dioxide (TiO2) film on biomedical titanium alloy (Ti6Al4V). This research is aimed at getting an ideal temperature range for forming a dense titanium dioxide (TiO2) film during titanium alloy cutting. This article is based on Gibbs free energy, entropy changes, and oxygen partial pressure equations to perform thermodynamic calculations on the oxidation reaction of titanium alloys, studies the oxidation reaction history of titanium alloys, and analyzes the formation conditions of titanium dioxide. The heat oxidation experiment was carried out. The chemical composition was analyzed with an energy dispersive spectrometer (EDS). The results revealed that titanium dioxide (TiO2) is the main reaction product on the surface below 900°C. Excellent porous oxidation films can be obtained between 670°C and 750°C, which is helpful to improve the bioactivity and osseointegration of implants.

- The versatility of rutile TiO2 extends beyond its physical and chemical properties. It can be modified through various surface treatments, such as doping with other elements or compounds, to enhance its performance in specific applications. For example, doping with nitrogen can improve the photocatalytic activity of rutile TiO2, making it more effective at degrading organic pollutants.
Titanium dioxide prices climbed significantly in the European region during Q2 2021, owing to strong demand from the downstream sector. Major global suppliers indicated that they have seen a surge in its demand for primarily from Europe and Asia, despite a global supply constraint. Furthermore, a global player raised titanium dioxide costs in Europe by 200 USD /MT this quarter, effective Q3 2021.
What other candies and food contain titanium dioxide?
Therefore, today, they only recommend limiting titanium dioxide inhalation in industries with high dust exposure, such as paper production (11).
