The chemical formula for titanium is simply denoted as "Ti." Titanium is a chemical element with the atomic number 22 on the periodic table and is classified as a transition metal. This lustrous metal is known for its strength, lightweight, and high resistance to corrosion, making it invaluable in a variety of industrial, aerospace, and medical applications. Unlike compounds, which have formulas representing the proportions of elements within them, pure elements like titanium are represented by their elemental symbols. Titanium's remarkable properties stem from its electronic structure and the way its atoms bond when it forms compounds or alloys, such as titanium dioxide (TiO2) or titanium alloy grades like Ti-6Al-4V.

The choice of oil grade for a fluid coupling is critical for its performance and longevity. Generally, manufacturers recommend specific grades or types, often ISO VG 32, 46, or 68 hydraulic oils, based on the operating conditions such as temperature and load. The selection considers factors like viscosity, which affects the transfer of power and heat dissipation. Synthetic oils are preferred in extreme conditions for their better thermal stability and longer life. It's essential to follow the manufacturer's guidelines or consult with a lubrication specialist to ensure compatibility and optimal functioning of the fluid coupling system. Regular oil checks and changes are also vital to maintain efficiency and prevent failures.

Although widely considered safe for use in non-ingested products such as cosmetics or sunscreens. the safety of titanium dioxide is uncertain when inhaled or ingested. The European Food Safety Authority EFSA recently conducted a reassessment of food safety and determined that titanium dioxide can no longer be deemed a safe food additive. This conclusion was reached due to concerns about genotoxicity and overall uncertainty regarding its effects on human health. Medical organizations globally are actively studying and monitoring these effects. With this in mind. it is advisable to consult with your physician or healthcare provider before incorporating any new treatments or substances. including titanium dioxide.
