BBIEN Tecnology supply 500g CASNo.7440-56-4 pure Germanium metal and Ge ingot 99.995% used for solder paste and making shiny joints

BBIEN high purity CAS No.7440-56-4 Germanium metal and Ge ingot 99.999%
Feature of rare metals Germanium
SHENZHENBBIEN TACHNOLOGY LIMITED supply gernanium metal 99.999% purity,its feature as following:
1. Customized zone refined Germanium or crystal particle size 200mesh typically for Ge powder
2. High purity raw material Germanium metal 5N, 6N,7N.
3. Wide range of application like metallurgy, chemical reagent organometallic compounds,
tetraethylgermane, which are useful in organometallic chemistry.
4. It is obtained from zinc ores and certain coals. Germanium is insoluble in dilute acid
and alkali, but soluble in concentrated sulfuric acid/nitric acid.
Other characteristics of Germanium metal
1. Crystal growth possible at lower temperatures.
2. Better forward voltage drop, only approximately 0.3V of germanium diodes.
3. Substantially higher electron and hole mobility indicating potential for higher-speed
