Our journey to a brighter, cleaner world
Tronox is one of the world’s largest producers of titanium dioxide and a leading producer of titanium chemicals. We are passionate about titanium, our employees and communities, and creating a cleaner, brighter future with the products we make.
TiO2 is all around you.
It is the white pigment in the paint on your walls, cars and kitchen appliances; in the plastic of bags, food packaging, window profiles, siding and flooring; in fine paper and laminate countertops, and many other applications. In its ultrafine form, TiO2 is used in specialty applications like ceramics and electronics, as well as in catalytic applications for industrial processes.
CristalACTiV™ is our ultrafine TiO2 product range for specialty applications from DeNOX and photocatalysis to energy storage, electronics and water treatment.
Explore Applications
Electronics
Outstanding electroceramics built from titanium
Titanium dioxide (TiO2) is the starting material for dielectric and piezoelectric materials such as barium titanate (BaTiO3), lead zirconium titanate (PZT), and other titanates used in multilayer capacitors (MLCC), thermistors and piezoelectric devices.
CristalACTiV™ TiO2 delivers the characteristics that precursors for electroceramic products need: purity, particle size and ease of milling.
Energy Storage
Titanium-based energy storage solutions for the future
There are many rechargeable battery chemistries available today, but none deliver the high cycle capacity, fast charge and discharge rates, and unparalleled safety characteristics of lithium titanate (LTO) batteries. Titanium dioxide is the starting point material for the manufacture of LTO batteries.
Photocatalysis
Creating a cleaner world
Photocatalysis is the acceleration with a catalyst of a naturally occurring reaction in the presence of light, water and oxygen. When TiO2 is exposed to UV light, free radicals are generated which facilitate reduction and oxidation reactions converting harmful materials such as nitrogen and sulphur oxides, VOC’s and organic matter into harmless substances.
CristalACTiV™ TiO2 is the key ingredients in many self-cleaning and depolluting materials.
Water Treatment
Cleaner water through the power of titanium
Access to clean water- whether for industrial, municipal, waste or drinkable water - is becoming a growing societal concern. There are multiple methods to purify water today, including filtration, flocculation, biological treatment, UV light treatment and photocatalysis.
Environmental Catalysis
Our technology, your process, a cleaner world
In response to growing concerns about the environment, NOx regulation is spreading globally. Selective Catalytic Reduction (SCR) has been widely adopted as the best available technology to reduce NOx from both stationary and mobile sources. The most effective SCR catalysts are based on TiO2. Cristal is a global technology leader with a complete product range of ultrafine TiO2-based products that can be adapted to meet customer needs.
Catalysis
A material of choice for catalyzing your reactions
CristalACTiV™ TiO2 based catalysts are used in numerous chemical catalysis applications. Examples include Claus catalysis which converts hydrogen sulfide (H2S) into elemental sulfur. Another example is the use of TiO2-based catalysts in gas-to-liquid reactions to make synthetic fuels.
Whatever the catalysis application, we have a TiO2 to fit your specific needs.
We’re always on the lookout for the next breakthrough
We are continuously developing new CristalACTiV™ materials to meet existing and future environmental regulations and respond to the needs of innovative applications.
