Product Details

Basic information

Germanium ingot is a high-purity metal material with germanium element as its core, with the chemical symbol Ge. It has a wide range of applications in semiconductor, infrared optics, solar cells and other fields. As an IVA group element, germanium has unique semiconductor properties with conductivity between metals and non metals. Its electrical properties can be adjusted through doping processes, making it an important foundational material for manufacturing diodes, transistors, and solar cells.
