It is important to note that titanium's hardness value on the Mohs scale of mineral hardness is not linear. Titanium's absolute hardness is approximately 36.

To create a colloidal suspension of titanium dioxide. begin by selecting the appropriate liquid for your specific requirements. For aqueous suspensions. combine a small amount of warm water with a small amount of titanium dioxide and gradually add more until it is fully suspended. Utilizing high-speed agitation if necessary. disperse any clumps that may form. If working with an oil-based liquid. the addition of a surfactant or dispersant may be necessary to avoid particle clumping and maintain stability in the suspension. Always follow safety precautions when handling titanium dioxide.

Polypropylene, a versatile thermoplastic polymer, is favored for its resilience to chemicals, water, and electricity, making it ideal for containers and packaging. Its fatigue resistance benefits repeated movement applications, such as hinges. Lightweight and easily moldable, it's used in automotive parts, textiles, and consumer goods, reducing manufacturing costs and enhancing product durability. Its ability to be recycled adds to its appeal, aligning with sustainability goals. The combination of practicality and environmental compatibility explains its widespread use.
