AMPERTEC® niobium pentachloride (NbCl5) - Purity and expertise

Chloride production is one of H.C. Starck Tantalum and Niobium's areas of special expertise. Our AMPERTEC® niobium pentachloride "Highest Purity" is the purest of its kind currently available on the market. AMPERTEC® niobium pentachloride is a highly reactive form of niobium. This characteristic is used in various applications like catalytic processes, chemical syntheses, coating and doping.

The chloride produced by H. C. Starck Tantalum and Niobium is also characterized by a larger particle size, which provides improved material flow characteristics. Moreover, the material is associated with less dust formation and improved storage capability due to reduced hydrolysis.

The main application for this product is its direct use as an ultrapure CVD precursor. The production of microprocessors and memory chips requires special CVD precursors made from AMPERTEC® niobium pentachloride "Highest Purity". Energy saving halogen lamps feature a heat reflecting layer made of AMPERTEC® niobium pentachloride. In the production of multilayered ceramic capacitors (MLCCs), AMPERTEC® niobium pentachloride provides support for powder design optimization. The sol-gel process used for this purpose is also applied in the production of chemically resistant optical coatings. Furthermore, AMPERTEC® niobium pentachloride is used in catalytic applications.
