Purified germanium is a'p-type' semiconductor material. Conductivity depends largely on added impurities. Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.Application: Isolated germanium is mainly used as asemiconductor material for transistors. The first generation of semiconductors were based solely on germanium. However, most of today's semiconductor production is based on silicon and germaniums use in electronics are in fibre-optic systems, infrared optics and in solar cell applications..Germanium and series products from Wuhan XinrongMaterial namePuritysizeHigh purity Germanium5N-7NGermanium Ingot5NGermanium powder5N100,200,325 meshGermanium Dioxide5N-6NGermanium shape and purity could be customized by customer requestPacking: After being packed in polyester films, then packed in plastic films or glass tubes in vacuum.GENERAL PROPERTIESSymbol:GeCas:7440-56-4Atomic Number:32Atomic Weight:72.59Density:5.323 gm/ccMelting Point:937.4 oCBoiling Point:2830 oCThermal Conductivity:0.602 W/cm/K @302.93 KElectrical Resistivity:microhm-cm @20 oCElectronegativity:1.8 PaulingsSpecific Heat:0.077 Cal/g/K @25 oCHeat of Vaporization:68 K-cal/gm atom at 2830 oCHeat of Fusion:8.3 Cal/gm moleTYPICAL ANALYSESImpurities in ppmMaterial /Purity:5N+Si0.9Cu0.5Gissing JiangWuhan Xinrong New Materials Co.,Ltdwww.91material.com
