The Kronos International is a chemical company and manufacturer of titanium dioxide . The headquarters are in Dallas , where the parent company Kronos Worldwide, Inc. also resides. The group's seven production facilities are located in five countries:
- Germany: Leverkusen and Nordenham
- Norway: Fredrikstad and Hauge i Dalane
- Belgium: Langerbrugge
- USA: Lake Charles
- Canada: Varennes
In Norway, the subsidiary Titania AS operates its own ilmenite mine, from which the raw material for titanium dioxide production comes.
The Kronos International is the fifth largest producer of world titanium dioxide - pigments and in Germany (about 100% subsidiary of Kronos Titan GmbH) largest producer. The production capacity is currently 550,000 t of titanium dioxide per year. The share of the world market is around 10 percent. Both the sulfate and the chloride process are used. The name Kronos comes from Greek mythology and describes the youngest and strongest of the titans .
The company's history begins in 1916 with the almost simultaneous commercial production of titanium dioxide in Fredrikstad (Norway) and Niagara Falls (USA). The TiO 2 pigment from the Norwegian plant was marketed under the name "Kronos Titan White" back then and was increasingly replacing the poisonous lead sulfate that had been in use as a white pigment. These two initially independent companies were taken over by the US conglomerate National Lead ( NL Industries , Inc.) in 1922 . In 1927, after the titanium company was founded in Leverkusen, the first of the two plants in Germany went into operation. The titanium company was then a joint venture between Bayer AG and later IG Farben and NL Industries. Important progress the company made in the years 1938/1939 to start manufacturing a rutile - modification of titanium dioxide , which fall mainly applies today. When IG Farben was dissolved after the end of the Second World War, the titanium company was completely taken over by NL Industries and renamed Kronos Titan-GmbH. In the 1950s and 1960s, new production facilities were built in Belgium, the USA and Canada. Finally, in 1969, the newest plant in Nordenham went into operation.
Kronos Titan-GmbH hit the headlines in 1980 when their tanker "Kronos" was prevented by Greenpeace activists from dumping so-called dilute acid into the North Sea on October 13 , which was officially approved at the time. Since the end of the approval for dumping on December 31, 1989, the company has been recycling the metal salt-containing sulfuric acid in an environmentally friendly manner .
The independent business division Kronos ecochem deals at the European locations of the company with the marketing of iron salts , which arise in large quantities as a by-product in the production process, mainly as iron (II) sulfate . Most of the salts are used in wastewater treatment (e.g. precipitation of phosphate ) and as a chromate reducer in cement .
