1.Main Application:Used to produce various types of germanium mono-crystalline materials.
2.Packaging:Melt germanium ingots cross-section is shaped as a trapezium,top width≥26mm,bottom width≥21mm,thickness≥23mmand length is between 100-500mm.Every ingot is vacuum sealed in a PVC layer bag,placed in a polystyrene box and then packaged in a wooden crate which is bound by steel cables.The net weight of each box is about 25kg.
3.Physical and chemical properties: Metallic Germanium is hard and brittle and has a silvery ash luster,atomic weight is 72.59,and density is 5.325g/cm3,melting point at 937.4°C and boiling point at 2800°C.
4.Transportation,storage and application
When delivering and storing melted Germanium ingots,it is important to protect the ingots from machining damage,humid and corrosive environments.
