History

The foundation of CeramTec goes back to the year 1903. At the time, Thomas works that have been taken over in 1908 by Philipp Rosenthal & Co. Ltd. emerged. These cooperated in 1921 with AEG in technical porcelain. This partnership was deepened in 1936 in the field of technical ceramics, it was the foundation of the insulators Rosenthal GmbH, also known as RIG.

1971 was established as part of a reorganization of cooperation Rosenthal Stemag Technical Ceramics GmbH for the production of technical ceramics. This company was renamed in 1974 in the Rosenthal AG, acquired in 1985 by Hoechst AG and Hoechst CeramTec out as from that date. In 1996 it was taken over by the Cerasiv GmbH, headquartered in Plochingen, the newly formed company operated as CeramTec AG.

The location in Lauf an der Pegnitz goes back to the founding of the Stemag AG ( steatite magnesia Aktiengesellschaft) in 1921. 1970 initially incorporated into the AEG, the company went on during the rearrangement of the partnership between Rosenthal and AEG in 1971 in the Rosenthal Stemag Technical Ceramics GmbH.

On Plochingen in 1951 as the Südplastik Rubber and Plastics Processing GmbH, which taken in 1953 by the field mill AG and Südplastik and ceramic GmbH ( SPK) has been renamed. In 1991, the field mill AG pooled their clay activities in the Cerasiv GmbH newly established, but this was sold in 1992 to Metallgesellschaft AG for integration into its subsidiary Dynamit Nobel AG. With the acquisition of Hoechst CeramTec by Cerasiv GmbH in 1996 saw the founding of CeramTec AG as a subsidiary of Metallgesellschaft AG ( mg technologies AG).

Metallgesellschaft AG was forced to part 2004 of its sub-group Dynamit Nobel AG. Main buyer was the American financial investor KKR, the parts of the Dynamit Nobel AG in its participation Rockwood Holdings Inc. integrated. This also CeramTec passed into the possession of Rockwood Group, headquartered in Princeton (New Jersey) in the United States, over. CeramTec AG grew as a company constantly on and acquired in 2007 by Emil Müller GmbH in Wilhermsdorf, which was incorporated as a subsidiary. Another acquisition was 2008: the ETEC Society for Technical Ceramics Ltd. was also incorporated as a subsidiary and renamed CeramTec -ETEC.

2013 separated Rockwood Holdings Inc. by several of his companies, the CeramTec Group was sold to the British private equity firm Cinven.
