Titanium dioxide is a kind of white pigment and functional material with excellent performance, which has excellent characteristics such as high refractive index, high light scattering, ultraviolet resistance and heat resistance. Titanium dioxide is widely used in coatings, plastics, paper, cosmetics and other industries, and its application in ceramic industry has gradually attracted attention in recent years. In the ceramic industry, titanium dioxide powder is mainly used in the production and processing of ceramic tiles, glazes, enamels and other ceramic products. By adding titanium dioxide, the luster, whiteness, wear resistance and ultraviolet resistance of ceramic products can be significantly improved, and their market competitiveness can be improved.

Basic Characteristics of Titania Tio2

Titanium dioxide is one of the whitest substances in the world, which has excellent hiding ability and high refractive index. This makes it outstanding in applications requiring high whiteness and hiding power, and can greatly improve the visual effect of products. According to the different crystal structure, titanium dioxide can be divided into rutile and anatase. Rutile titanium dioxide has higher stability and light resistance, so it is more widely used in ceramic industry. Its characteristics are as follows:

High refractive index: Rutile titanium dioxide has a refractive index as high as 2.7 and is one of the most commonly used high refractive index pigments in the market.

Chemical resistance: Rutile titanium dioxide has strong corrosion resistance to acid and alkali, and can remain stable in the high temperature firing environment of ceramics.

Strong hiding power: its strong hiding power makes it possible to achieve ideal whiteness effect with a small amount of addition, thus saving costs.

Good dispersibility: the particles of titanium dioxide are fine and easy to disperse, which is convenient for uniform distribution in ceramic glaze and other materials.

Application Field of Titanium Dioxide Powder in Ceramic Industry

Ceramic Glaze

In ceramic glaze, the main function of tinox tio2 is to increase the whiteness, gloss and hiding power of glaze. Especially in the production of ceramic tile glaze, adding appropriate amount of tinox tio2 can enhance the surface luster of ceramic tile and make it brighter under illumination. Due to the excellent ultraviolet resistance of titanium dioxide powder, the surface of ceramic tile is not easy to fade, which prolongs the service life of the product.

Ceramic Pigment

As the basic material of ceramic pigments, titanium dioxide is widely used in ceramic decoration. Its whiteness and hiding power provide an ideal color base for ceramic products and make the coloring effect of other color pigments more uniform. Titanium dioxide is not only used in white ceramic products, but also can be used as toner and filler for other color ceramic pigments.

Architectural Pottery

In the manufacture of building ceramics (such as wall tiles and floor tiles), titania tio2 is often used for glaze treatment. By adjusting the dosage and formula of titanium dioxide, different styles of ceramic surface effects can be produced. In addition, the excellent wear resistance of titania tio2 makes building ceramics perform well in outdoor and high wear environment, and prolongs their service life.

Art Ceramics

Art ceramics pay attention to visual effects, and the addition of titanium dioxide makes its surface more beautiful and shiny. In the application of over-glaze color and under-glaze color, the hiding effect of titanium dioxide makes art ceramics keep bright colors after high temperature firing.
