The company founded in 1922 by Max Schaidhauf in Sankt Mang as Elektroschmelzwerk Kempten (ESK) in the legal form of a stock corporation began in 1925 with the production of silicon carbide . The Dr. Alexander Wacker Gesellschaft für Elektrochemische Industrie took over the majority of ESK shares in 1933. After a fire in 1936, the company was rebuilt with a higher number of employees. In 1940 boron carbide was produced for the first time .
Due to a shortage of electricity, the smelting operation was relocated to the branch in Frechen-Grefrath in 1952 . It was converted into a limited liability company . In 1955 the melting plant was completely outsourced to Grefrath.  The production of mixed ceramics for metallization began in 1962. Ten years later, the surface was refined with nickel-diamond.
In 1977 the production of silicon and boron carbide components on the basis of pressureless sintering succeeded . In 1979 the world's first hot isostatic press was put into operation at temperatures above 1900 ° C for the production of non-oxide ceramics. In 2001 two hot presses with a pressing force of 600 tons were completed.
