NIOBIUM AND TANTALUM “HIGH PURITY” POWDER - Highest degree of purity and ductility
Highly pure niobium and tantalum metal powders by H.C. Starck are used when the situation depends on the highest degree of purity and ductility. Because they also feature a high level of temperature resistance, small grain sizes and a high degree of biocompatibility, and are inert with respect to many aggressive media, they are primarily used in the electronics industry, medical technology and for alloys.
"High Purity" powders by H.C. Starck play a particularly critical role in the electronics industry. Due to their high degree of purity and high quality, these materials are important for effectively igniting many types of flash bulbs, which are used in aviation, in warning lights and for mobile phone and smartphone cameras. Sputter targets used in the production of smartphone touchscreens and other touch-sensitive user interfaces are another main application.
Our tantalum and niobium "High Purity" powders are used in aviation and energy industry applications as alloy additives for corrosion-resistant turbine blades. In medical technology, they are used as radiographic contrast agents and in the production of bone replacement material and implants.
Tantalum from certified suppliers from conflict-free sources
H.C. Starck only processes raw materials from ethically acceptable, conflict-free sources. This also applies with respect to the procurement and processing of tantalum. We only purchase raw materials that meet the specifications of the OECD ("Due Diligence Guidelines for Supply Chains of Minerals from Conflict-Affected and High-Risk Areas"). Our company and its tantalum processing sites are certified in the context of the Conflict-Free Smelter (CFS) Validation Program of the independent Electronics Industry Citizenship Coalition (EICC) and the Global e-Sustainability Initiative (GeSI).
Thanks to innovative recycling processes, we are able to reclaim tantalum from almost any type of scrap with a tantalum content of 1 to 99 percent, which also ensures the supply of raw materials and provides the customers of our tantalum-recycling program with greater independence from fluctuations in supply and price. As part of our “closed-loop-offer” we also accept used, recyclable tantalum containing products from our customers and reprocess them to produce high-performance tantalum powders.
