Q structure of titanium dioxide nanoparticles

GroverDavid Release Time: March 21, 2024, 10:07 PM
TiO2 nanoparticles are typically spherical and consist of small titanium dioxide particles in crystalline form. They have three crystal structure phases: anatase. rutile. and platelet titanite. Anatase is the most common phase with a tetragonal crystal system and two molecular units per cell. Its structure is a tetragonal deformation of the cubic fluorite structure. Rutile. on the other hand. has a denser square structure and is thermodynamically stable. It is commonly synthesized under high temperature and pressure. Platelet titanite. with its rhombohedral structure. is the third most prevalent polycrystalline material among TiO2 nanoparticles. These particles are known for their high refractive index. strong UV absorption. and potential size-dependent properties due to quantum size effects. The size of titanium dioxide nanoparticles typically ranges from 1 to 100 nanometers nm but can be controlled during manufacturing.

Titanium dioxide is generally considered safe for use on lips. It is an FDA-approved ingredient often used in cosmetics like lip balms and lipsticks for its pigmenting and sun-protecting properties. However, the main concern is inhaling titanium dioxide particles, which can be harmful, especially in its raw powder form. To minimize risk, don’t use loose powders containing titanium dioxide. Despite these precautions, most dermatologists agree that the levels used in cosmetics pose minimal health risks.

Titanium dioxide is a frequently utilized ingredient in personal care items. including deodorants. due to its ability to reflect light and result in a white. opaque appearance. In addition to providing color. it also functions as a sunscreen by blocking harmful UV rays. However. there is an increasing apprehension about potential health hazards associated with nanoparticles that may penetrate the skin. While the FDA deems it safe for cosmetic use. certain manufacturers have chosen to discontinue its usage due to these concerns. If you prefer to avoid this component. it would be wise to examine product labels carefully.

Q ilmenite extraction process

Ilmenite is a natural mineral sand containing high levels of both titanium and iron. To extract the valuable ilmenite. a series of steps must be taken. The first step. mining. involves extracting the mineral sands from the ground via open pit mining. dune dredging. or beach dredging. Next. the sand undergoes concentration where it is cleaned and screened to separate the heavier ilmenite from lighter sand and clay particles using gravity spirals. The concentrated titanium ore slurry is then transported through a slurry pipeline to a wet concentrator for further refinement into a higher grade concentrate.
