These small, precision cast indium units are the product of an innovative processing technology based on vacuum induction melting. Available in a number of customised forms, these ingots are ready-to-use for the epitaxial layer preparation of III-V compounds; used in semiconductors for high-speed electronic and optoelectronic applications. Ingots are offered in a range of metal purities, from 6N (99.9999%) towards 7N metal.

Purity
Ingots are available as 6N, 6N5 or >6N8 pure (metals basis)
Packaging
Ingots are packed individually into vacuum-sealed, multi-layered aluminised laminate packs, providing excellent protection and long shelf-life.
Price and availability
In general, materials are produced to order with typical lead times varying from 3 to 6 weeks depending on the required ingot size, purity and order quantity.
Quality assurance
Indium metal products are analysed independently by GDMS (Glow Discharge Mass Spectrometry). Results are reported on a Certificate of Analysis with each consignment.
