Unfortunately, we studied that all of the above methods are employed after machining or forming, and they require a long process chain and costly production types of equipment [2124]. Therefore, we proposed a titanium alloy implant preparation process that integrated with cutting and surface modification. The oxygen-rich atmosphere increases the partial pressure of oxygen in the oxidizing environment, and the heat generated during the cutting process increases the temperature and the rate of the oxidation. It uses the cutting heat and oxygen-rich atmosphere generated during the cutting process to form the oxide film (TiO2) to improve the corrosion resistance of the titanium alloy. The experimental equipment is shown in Figure 2. Since the cutting temperature is the most important factor in the oxide film formation process, this paper carried out researches based on theoretical analysis and experimental investigation to acquire an ideal temperature range for the cutting process to achieve the oxide layer.

Gravimetric analysis is a method of quantitative chemical analysis in which a substance is converted into a stable compound of known composition, and the mass of this compound is then measured. This technique offers a high level of precision and is particularly useful in determining the concentration of materials within complex mixtures. The gravimetric determination of titanium dioxide typically involves a series of well-defined steps, which include precipitation, filtration, washing, drying, and weighing.

The determination of sulfate in various matrices is a critical task for environmental monitoring, industrial process control, and quality assurance in chemical production. When present in high concentrations, sulfates can pose health risks and impact the ecosystem. However, the analytical challenge often lies not just in detecting the presence of sulfates but also in accurately quantifying them, especially when they are to be determined as titanium dioxide (TiO2). This article delves into the methodologies used to determine sulfate as TiO2, highlighting the complexities and nuances involved in such an analysis.

Suppliers play a crucial role in transforming these raw materials into usable titanium dioxide. They employ specialized extraction techniques such as the Becher process for ilmenite or the sulfate process for rutile and anatase, which involve chemically treating the ore to produce titanium dioxide. In the sulfate process, for example, the ore is treated with sulfuric acid to form titanyl sulfate, which is then calcined to yield titanium dioxide.

  • Furthermore, the use of titanium dioxide in water purification systems is another example of how this mineral contributes to environmental sustainability. With its strong oxidative properties, titanium dioxide can effectively remove pollutants and contaminants from water, making it safe for consumption. By incorporating titanium dioxide into water treatment processes, China is able to provide clean and safe drinking water to its citizens.
