Titanium dioxide

Description

Titanium dioxide is an inorganic compound with the formula Tio₂, commonly known as titanium oxide IV or titania. The chemical composition of titania is one of the most widely used mineral pigments in the industry and the most important consumers of this mineral salt are the paint and coating industries, and paper and plastics industries. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

Physical and Chemical Properties:

Titanium dioxide is the most important white pigment, which in addition to coloring the particles, also has a protective effect against UV. This material has two forms of allotropy rutile and anatase, which due to its white color, high refractive index, excellent luminosity, ineffectiveness (neutrality) and high abrasion and heat resistance, high refractory degree, and High power in uniform distribution and diffusion in other compounds are known as the main and most important raw material of white paint in the industry; in the table below some of the chemical and physical properties of this product are mentioned:

The Production Process of Titanium Dioxide :

The method of producing titanium dioxide depends on the raw materials available. The most common source of titania is the mineral compound ilmenite with the formula FeTiO3. After the ore of this material is extracted, it must be converted to its pure form through two processes, ‘sulfate’ and ‘chloride’.

Sulfate Process:

In this process, laminate (FeTiO₃) is a common source for the production of the product, which reacts with concentrated sulfuric acid to extract titanium oxygen sulfate (TiOSO₄) and eventually converts it to TiO₂.

Chloride Process:

This process requires the purest ore available or rutile, which is very rare. Raw materials must contain at least 70% rutile. Titanium is first oxidized by reacting with carbon and then repeated with chlorine. The resulting TiCl₄ liquid is distilled by contact with a pure oxygen flame or plasma at a temperature of 1200 to 1700 ° C and converted to TiO₂.

Titanium Dioxide Uses:

In this section, we describe some of the uses of this chemical:

Paint:

Titania is also used in the production and manufacture of various paints. Its presence in the color structure makes the paint more durable and increases the life of the paint on the surfaces. It also prevents the paint from fading over time. like Butyl di glycol

Cosmetics:

Titanium dioxide such as betaine is used to make and produce a variety of cosmetics such as eye shadows, blushes, compact cosmetic powders, and various creams such as sunscreens. The presence of this compound in the structure of creams and some cosmetic powders helps to lighten the skin and remove skin blemishes.

Food:

Titanium dioxide is a non-toxic and safe substance for humans. For this reason, this chemical is used as a color additive and is used to increase the whiteness of some compounds such as dairy products, and candies and increase the transparency of toothpaste and some drugs. It is also used as an authorized flavoring for dried vegetables, nuts, seeds, soups, mustard, and alcoholic beverages such as beer and wine.

Plastics, Adhesives, and Rubber:

Titanium dioxide can help minimize the brittleness, fading, and cracking that can occur in plastics and other materials when exposed to light.

Buy Titanium Dioxide:

Titanium dioxide is produced in different types and each type has its own price. For detailed information on the price of titanium dioxide, you can contact our consultants in the Shanghai Chemex sales department, and in addition to the price, be aware of the available types of this material.

Safety Information:

This inorganic compound is safe in terms of flammability and toxicity but can cause irritation or allergies in the respiratory system. Workers who deal with this mineral pigment may suffer respiratory injuries in the long run. Thus, it is recommended to use gloves, masks, special work clothes, and safety glasses when working with this chemical compound.

Packing and Storage:

Titania packaging bags should be stored in dry, cool, well-ventilated warehouses away from heat or fire.
