Main Application: Used to produce various types of germanium mono-crystalline materials.
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.
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℃ and boiling point at 2800℃.
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.
