The production process of TiO₂ pigment comprehends two steps. The first step is the production of the base material. In the second step, the post treatment (see section Post Treatment (PT) ), the base material is coated to add additional properties like dispersibility or weatherability.

Two technologies are available for the production of the base material: The sulphate process (see section Sulphate Process (SP)) and the chloride process (see section Chloride Process (CP)).

In the sulphate process (SP) sulphuric acid is used. This process was developed in the 20’s of the last century.

In the chloride process (CP) chlorine is used. The process was developed in the 50’s of the last century.

Ti-Cons offers the technology for SP, CP and PT.

The following tables shows the advantages and the disadvantages of SP and CP:


Chloride Process (CP)	Sulfate Process (SP)
Less flexible due to raw material quality	Wider range of raw material – especially Ilmenite – available
Better product quality regarding the optical and chemical properties	Product quality regarding the optical properties of Rutile base material is lower
Production of anatase pigment is not possible	Production of anatase pigment is possible
Smaller buildings	Larger buildings
Fewer vessels	More vessels
Less man power necessary	More man power necessary
Higher requirements to the qualification of the staff	Lower requirements to the qualification of the staff
Continuous Process	Mainly batch process
Less environmental impact due to less waste	More environmental impact due to more waste
Possibility to rework some of the waste to sellable co-products	Process needs co-product management and attractive markets for co-products
Requires stable production environment and infrastructure	Process is easier to handle because of batch process
Less amount of co-products	High amount of co-products
Because of the closed loop the process is more sensitive	Production does not stop totally if one step fails
Higher safety requirements due to the use of Cl2 and TiCl4	Lower safety requirements. In case of use of disulfuric acid, higher safety requirements are necessary
Higher degree of automation necessary	Lower degree to automation can be sufficient
Generally the production costs are lower.	Generally the production costs are higher.
