With the progress of nanotechnology, nano-titanium dioxide powder has been applied in ceramic industry. Nano-titanium dioxide powder has small particle size, large specific surface area, good light scattering performance and efficient anti-ultraviolet function, which makes the ceramic surface more bright and color stable. Its superior dispersibility also helps to distribute evenly in the ceramic substrate and reduce the formation of pores and defects.

Technical Progress in Application of Titanium Dioxide Powder in Ceramic Industry

Surface Treatment Technology

By modifying the surface of titanium dioxide powder, its dispersibility and affinity in ceramic glaze can be effectively improved. Commonly used surface treatment methods include silanization and aluminization, which can significantly improve the compatibility of titania tio2 in glaze, prevent particle agglomeration and make ceramic glaze more uniform and smooth.

High Temperature Sintering Process

Ceramic products need to withstand high temperature in the firing process, and the traditional titanium dioxide powder may undergo phase change or fade at high temperature, which will affect the quality of the final product. In modern technology, many enterprises begin to use modified titanium dioxide powder or rutile titanium dioxide powder with higher stability to ensure that it can still maintain whiteness and brightness after high temperature sintering.

Research and Development of High Transparency Titanium Dioxide Powder

In order to make ceramic products more translucent while maintaining whiteness, some enterprises have developed titanium dioxide powder with high transparency. By controlling the grain size and reducing particle aggregation, transparent titanium dioxide powder can improve the light transmittance of ceramic glaze and make the underglaze color more vivid without affecting the hiding power.

Advantages of Titanium Dioxide Powder in Ceramic Industry

Improve Product Appearance

The high hiding power and high gloss of titanium dioxide powder make the surface of ceramic products more beautiful and increase the market competitiveness of products. Its yellowing resistance and ultraviolet resistance make ceramic products difficult to fade and yellow in long-term use.

Improve Durability

Titanium dioxide powder can enhance the weather resistance, wear resistance and impact resistance of ceramic products, so that they can maintain good performance in indoor and outdoor environments, and are suitable for long-term use under conditions of high wear or high temperature and humidity.

Cost-Effectiveness

Although the cost of titanium dioxide per kg is relatively high, its high hiding power and whiteness make it possible to achieve the ideal effect by adding a small amount, thus saving the amount of other additives. Compared with other pigments or white fillers, titanium dioxide powder has higher cost performance.

Challenges Faced by Titanium Dioxide Powder in Ceramic Industry Application

Environmental Pressure

Because the production process of titanium dioxide powder will produce a certain amount of waste and by-products, the tightening of environmental protection regulations has brought great pressure to production enterprises. In order to meet the requirements of environmental protection, some enterprises need to invest in environmental protection equipment and process improvement, which increases the cost.

Fluctuations in Prices

Due to the influence of raw materials, energy prices and market supply and demand, the titanium dioxide price may fluctuate. For ceramic manufacturers, how to effectively control costs and reduce the impact of price fluctuations on production is an important challenge.

Competition of Substitutes

Although titanium dioxide powder has excellent properties, there are some potential substitutes in the market, such as white fillers such as aluminum silicate. Although these substitutes are inferior in hiding power and whiteness, they have certain advantages in cost.

In the fierce market competition, titanium dioxide manufacturers will pay more attention to the research and development of high-performance and low-cost titanium dioxide producers to improve market competitiveness. By optimizing the production process and developing new titanium dioxide powder materials, titanium dioxide vendor can provide more cost-effective material selection for ceramic industry.

With the progress of nanotechnology and green manufacturing technology, the application of titanium dioxide powder in ceramic industry will be more extensive and in-depth, which will promote the development of ceramic industry in a more efficient and environmentally friendly direction.
