Wholesale Nano Mn2o3 Powder - 99.99% GeO2 Germanium Dioxide powder – Xinglu
Wholesale Nano Mn2o3 Powder - 99.99% GeO2 Germanium Dioxide powder – Xinglu Detail:
Features
1. Germanium dioxide is a stable, white powder that is most commonly extracted from sphalerite zinc ores and lignite coal fly ash.
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).
