The story
The founding of CeramTec goes back to the year 1903, when the Thomas factories (Thomaswerke) were founded at the Marktredwitz site, and which were taken over by Philipp Rosenthal & Co. AG in 1908. In 1921 Philipp Rosenthal & Co. AG began cooperating with AEG in the development of technical porcelain for early industrial applications of ceramic materials. The two companies intensified this partnership in the area of technical ceramics in 1936, resulting in the foundation of Rosenthal Isolatoren GmbH, also known as RIG.
With the intention of manufacturing technical ceramics, they reorganized their cooperation in 1971. The result was the company Rosenthal Stemag Technische Keramik GmbH, which was renamed Rosenthal Technik AG in 1974. In 1985 Hoechst AG acquired the company and from that point on operated it under the name Hoechst CeramTec AG. Cerasiv GmbH, a company based in Plochingen, took over Hoechst CeramTec AG in 1996 and the newly formed company received the name CeramTec AG.
The site in Lauf an der Pegnitz has its roots in STEMAG AG (Steatit-Magnesia Aktiengesellschaft), founded in 1921. Following an initial incorporation into AEG in 1970, the company merged into Rosenthal Stemag Technische Keramik GmbH in 1971 as part of the reorganization of the partnership between Rosenthal and AEG.
Südplastik Gummi- und Kunststoffverarbeitung GmbH began operations at the Plochingen site in 1951. Feldmühle AG took over the company in 1953, renaming it Südplastik und -keramik GmbH (SPK). Feldmühle AG refocused its ceramic activities in 1991 in the newly founded Cerasiv GmbH, but then quickly sold it in 1992 to Metallgesellschaft AG, which integrated the company into its subsidiary Dynamit Nobel AG. Cerasiv GmbH’s acquisition of Hoechst CeramTec AG followed in 1996, resulting in the founding of CeramTec AG as a Metallgesellschaft AG (mg technologies AG) company.
Metallgesellschaft AG’s subgroup Dynamit Nobel AG broke away from Metallgesellschaft AG in 2004. KKR, an American private equity firm, became the main buyer, integrating parts of Dynamit Nobel AG into Rockwood Holdings Inc. In the process, the US-based Rockwood group took over ownership of the CeramTec AG group. CeramTec continued to grow, acquiring and integrating Emil Müller GmbH (Wilhermsdorf, Germany) into the company as a subsidiary in 2007. A further acquisition followed in 2008; ETEC Gesellschaft für technische Keramik mbH also became a subsidiary and was renamed CeramTec-ETEC GmbH.
In 2013, Rockwood divested several of its companies and the CeramTec group was acquired by the British private equity firm Cinven.
In 2017, CeramTec acquired Morgan UK ElectroCeramics with its two sites in Southampton and Ruabon to complement its existing product portfolio in the field of sensors, capacitors, transducers and piezo ceramics.
In 2017, Cinven sold the CeramTec group of companies to funds advised by private equity investor BC Partners and other co-investors for a purchase price of EUR 2.6 billion.
