The Process of Producing and Obtaining High Purity Germanium
Germanium, stamped with the atomic number 32 in the periodic chart, is a metalloid of greyish-white hue and hard consistency. Its unique characteristics make it indispensable across multiple sectors. It’s chiefly discovered within sphalerite zinc ores and coal but can as well be derived from copper, silver, and lead ores. The germanium extraction process is an intricate one requiring refining to attain high purity.
The beginning stage in germanium production involves roasting sulfide ores with minute traces of germanium at elevated furnace temperatures to form GeO2 or germanium dioxide. This compound then undergoes further refinement using hydrochloric acid leading to the formation of GeCl4 or germanium tetrachloride – an intermediate product that will eventually yield elemental Germanium. At this juncture, it’s worth noting that reactions between hydrogen chloride and GeO2 often result in side products such as Germanium hydride and tetrahydride.
To acquire crystalline forms of Germanium for semiconductors or single crystals thereof, subsequent steps involve reducing GeCl4 using hydrogen gas at extremely high heat – thus deriving pure versions of this invaluable metalloid referred to as “zone refined” ultra-high-purity metallic or elemental Germanium. Despite its prominent role since its discovery within the semiconductor industry, large-scale production only took off post World War II replacing other materials like silicon in transistors owing to superior performance features offered by crystalline variants for specific end uses including solar cells applications among others along with infrared optics.
