Another focus of production are ceramic powders , sintered metal powder , thermal spraying powder , non-ferrous metals, nickel and cobalt and its salts, and boron and boron compounds.

The subsidiary HC Starck Ceramics GmbH manufactures machine and engine components as well as foundry products made from silicon carbide , silicon nitride , aluminum titanate , zirconium oxide and aluminum oxide . The HC Starck Ceramics R&D laboratory carries out material tests and process developments.


The company was founded in 1920 by Hermann Carl Starck as a trading company for metals and ores in Berlin and in 1935 took over the majority of shares in the Goslar company Chemische Fabrik Gebr. Borchers AG. The founding and environmental history of HC Starck as well as the production during the Nazi era were presented by Knolle & Schyga (2012).

From 1986 to 2007, HC Starck belonged to the Bayer Group (whose plastics division Bayer Material Science was renamed Covestro in 2015 ). In February 2007 Bayer sold HC Starck to the financial investors Advent International and Carlyle Group for 1.2 billion euros . During this time the company was held by a holding company in Luxembourg (Opus Investment).

The time after the sale was marked by restructuring and the sale of parts of the company. Numerous jobs were cut in 2008, 2010 and 2015. In 2007 the business with battery products was sold to the Japanese company Toda Kogyo, in 2008 the silica sol business to Akzo, in 2010 the business with the conductive polymer Clevios to Heraeus, and in 2017 the business unit Surface Technology and Ceramic Powders to the Swedish company Höganäs , and in 2018 the Tantalum and Niobium division to the Japanese JX Nippon Mining & Metals. In 2010 a joint venture with Japan New Chisso Corporation was established, which was dissolved in 2018. In 2011, two joint ventures were established with Jiangxi Rare Metals Tungsten Holding Group Co. Ltd. in China and in 2013 a joint venture with Nui Phao Mining in Vietnam. This last joint venture partner took over the tungsten production of the HC Starck Group in 2019. The infrastructure company Chemitas, which operates at the Goslar location, was also sold. The engineering ceramics plant and business in Selb was sold to Kyocera (Japan). After the sale of the companies outside the USA, HC Starck only operates there (production of sintered parts from molybdenum and tantalum and production of so-called tungsten heavy metal) in the plants in Coldwater (OH) and Newton near Boston.

The total turnover of the HC Starck Group fell from 905 million euros in 2007 to 688.4 million euros in 2016.


The company was founded in 2001 by the Association Coalition against Bayer Dangers accused (CBG) that with tantalum from the Congo is, thus supporting the Congolese rebel troops. The UN counts the company among the largest buyers of tantalum. The export proceeds from the raw materials enable the rebel troops to finance the civil war in the Congo . The UN therefore called for an import ban on tantalum from the Congo. In its final report, however, a United Nations investigative body assessed the allegations made against the company as follows: "Category 1 - Resolved - No further Action required". HC Starck has its raw material sources for tantalum in Australia and recycles certain tin slag from Asia. No tantalum raw materials are bought in the DRC .
