Preparation of germanium dioxide from waste residue of zinc sulfate;

The results show that the high-purity germanium dioxide(or germanium tetrachloride) may be produced by the second chlorination distillation.

Study and Fabrication of GeO_2 Hollow Core Fiber;

Control of arsenic content in the production of high-purity germanium dioxide;

A new method in which trace arsenic in high-purity germanium dioxide is determined using silver nitrate absorption photometry is described in this discussion.
