Ultrafine titanium dioxide

Titanium dioxide is one of the most widely used inorganic materials in the world. The most common form is pigmentary titanium dioxide but in recent years there has been a growing demand for ultrafine titanium dioxide. Ultrafine titanium dioxide is known for its many and versatile applications emanating from its very small particle size and semiconductor nature. These include UV absorbing transparent coatings, flip-flop automobile coatings, plastics additive, cosmetics UV blockers and electronic components characteristic mainly for rutile ultrafine particles. Anatase based applications are even more versatile and include photocatalysis (self-cleaning effect, decomposition of harmful nitrous oxides from automobile exhausts, water and air purification), photoelectrochromic windows, DSSC (“dye-sensitized solar cells”) and many more.

The range of use of ultrafine titanium dioxide is extremely wide and growing annually.

Cinkarna Celje is centered in continuous development of the above stated applications to meet existing and future demands relying on global reach and strong scientific base which put ultrafine TiO2 products at the core of our activities.

The elementary principle of our ultrafine TiO2 is the sulphate synthesis process, which is upgraded for the synthesis of final ultrafine product. In Cinkarna Celje we decided for strategicall orientation towards the production of ultrafine TiO2 explicitly in water suspension form. For that reason we have already developed the synthesis methods for anatase and rutile ultrafine particles that we obtain in suspension form without any intermediate powder phase. Decision is based on mastering the fine particles which stay in the suspension and on care for the healthy working conditions of the employees and the users of product. With the production of ultrafine TiO2 products exclusively in suspension form, we prevent negative influence on environment (emission of nanoparticles). With our synthesis methods we can control reaction mechanisms and that gives us control over the most important parameters of ultrafine particles, namely particle size, surface treatment and the crystal structure. Those parameters enable us to adapt ultrafine TiO2 particles characteristics to best fulfill demands of the above mentioned applications.
