Germanium is considered expensive due to several factors that influence its supply, demand, and overall market dynamics:
- Scarcity of Sources: Germanium is not found in its elemental form in nature; instead, it’s typically extracted as a byproduct of zinc ore processing or from other minerals like coal, copper ores, and silver. Because its production is tied to the mining of these primary metals, the availability of germanium is dependent on the scale and economic viability of mining operations for these other materials.
- Complex Extraction and Refining Processes: The process of extracting germanium from its ores and further refining it into a pure, usable form is complex and costly. High-purity germanium, especially the type used in electronics and optical applications, requires sophisticated technology for refining, which adds to the cost.
- High Demand in High-Tech Applications: Germanium is critical in several high-technology applications, including fiber optics, infrared optics, solar cell technologies, and some specific semiconductor devices. The high demand in these specialized and expanding sectors puts pressure on the limited supply, driving up prices.
- Market Control: A few countries and companies control a significant portion of the world’s germanium production. This limited number of suppliers can influence the price by controlling the production rates and the amount of germanium entering the market.
- Purity Requirements: The specific applications for which germanium is used, such as in optical systems and semiconductor devices, require very high levels of purity. Achieving and maintaining this purity level involves additional processing steps and quality control measures, which further contribute to its high cost.
Because of these factors, the price of germanium remains relatively high compared to more abundantly available materials.
