1. Germanium dioxide is a stable, white powder that is most
commonly extracted from sphalerite zinc ores and lignite coal fly
2. Germanium concentrates can be treated via a chlorine
distillation method that produces germanium tetrachloride (GeCl4).
3. This can then be hydrolyzed to GeO2.
4. This form of germanium dioxide has a hexagonal crystal structure
and is soluble in water at a rate of 4.5g per litre (25°C).
