• All chemicals containing organic matter and environmental hazards are used in titanium dioxide nanoparticles. The titanium dioxide nanoparticles purchase by various industries is to improve the quality of the product produced by these industries. Most chemicals companies use these chemicals in their products.
Who are the best producers of nanoparticles?
In recent years, Iran has been producing titanium dioxide nanoparticles that can be used for solar cells, photocatalysts, self-cleaning glass and ceramic pigments.
China and the United States top the list of manufacturers and exporters. There are various methods for the preparation of titanium dioxide powder, including: sulfate, chloride, liquid gas neutralization, TiCL4 oxide flame synthesis and sol gel method.
This material is used in a variety of industries such as: textile industry that uses different colors to dye fabrics. The use of these colors has caused pollution in the environment around us. To reduce these contaminants, specialists in the use of titanium dioxide nanoparticles have been able to reduce the environmental pollution caused by the use of these dyes and take a major step forward in the textile industry.
The use of titanium dioxide nanoparticles in today’s industry has significantly reduced air pollution. The most important uses of different industries are titanium dioxide nanoparticles to reduce environmental factors and improve air quality, which is one of the major concerns of various countries these days.
Air pollution has increased respiratory and heart disease and in the cold days of winter due to temperature inversion these effects are more likely to be life threatening.
How to identify purity of nanoparticles?
In many cases, TIO2 is produced by sulfate or chloride reactions, but the particles are coarse (in the micron range) and have little purity. The concentration of these nanoparticles in the products depends on their quality.
Titanium dioxide nanoparticles are used in a variety of products and have a different purity percentage that can be obtained by searching the product name on the Internet and can also be determined by the company. For example, sunscreen, they often contain 25% of titanium dioxide nanoparticles.
When we use it as a food color, it’s number is 171.The titanium dioxide solubility in different solvents is not the same. For example, it dissolves very well in water (H2O).
Titanium dioxide has eight oxidation modes, including: rutile, anatase, and brucite – three-phase, which can be synthesized. Titanium dioxide color is widely used as a white pigment because of its high luminosity and high coefficient. This compound shows photocatalytic activity in the presence of light with energy equal to or greater than the molecular bond energy.
Titanium dioxide nanoparticles major consumers in the world
The most important uses of titanium dioxide are paint, varnish, paper and plastic, which make up a high percentage of the world’s titanium dioxide consumption.
Other uses of pigments include printing on textiles, fibers, rubber, cosmetics, and food, which include a small percentage. Others are used in other applications such as the production of pure titanium, glass ceramics, electric ceramics, catalysts, electrical conductors, and chemical intermediates.
There is also a lot of titanium dioxide in red candies.
Titanium Dioxide Nanoparticles in Food
Certain types of titanium dioxide pigments have been approved in accordance with appropriate purity standards as colors in foods (such as candy, biscuits, pastries, coffee whites, toothpaste, etc.) and various types of medicines.
The use of titanium dioxide is very common in our society. Most surfaces and white items have titanium dioxide, so we are surrounded by this chemical that is found in homes, businesses and public places.
Since the introduction of titanium dioxide as an economic product in 1923, there has been no health concern for people who want to use it in a variety of ways. For decades, this product has been known safely for various applications. The tio2 price in manufacturing companies differs from its market price and these centers provide it at a cheaper price.
