| Processing
|
- Transformation of Germanium compounds to
GeCl4.
- Our factory can return scraps from optical
fiber production to GeCl4.
- Fractionated distillation and rectification
of GeCl4 to arrive at high purity product, 99.9999%
for fiber optic grade.

| Germanium
Tetrachloride is soluble at 25oC in acetone, benzene, Carbon
disulfide, carbon tetrachloride, chloroform, and diethyl ether. It
is slightly soluble at concentrated hydrochloric acid, insoluble in
concentrated sulfuric acid and decomposes in water. |
