About CONDIAS
CONDIAS GmbH, based in Itzehoe (Schleswig-Holstein), produces polycrystalline diamond coatings and products based on them. At its core is the hot-filament CVD process (chemical vapour deposition), which deposits boron-doped diamond coatings on substrates such as niobium, tantalum, silicon, graphite, molybdenum, titanium carbide and conductive ceramics – on areas up to 100 × 50 cm². From the conductive coatings, the company manufactures DIACHEM® diamond electrodes to customer specifications (plates, expanded metals, rods; layer thicknesses up to 15 µm) as well as electrolysis cells for disinfection (CONDIAPURE®, MIKROZON®), oxidative wastewater treatment (CONDIACELL®) and electrochemical synthesis (SSZ series, RED OX®). The basis is the company's own EAOP® process, in which oxidants such as ozone and hydroxyl radicals are generated directly from water. In addition to production at the Hightech Itzehoe technology site, CONDIAS offers process development, feasibility studies, pilot plant construction, and spectroscopic, ion chromatographic and microbiological analysis (S2 laboratory). Fields of application include water treatment, disinfection, semiconductor manufacturing, pharmaceuticals/cosmetics, the automotive industry and green chemistry.
