How we can separate TeO2 from SiO2 ?
The specific gravity of TeO2 is 5.9. Alpha quartz is the densest form of silica and has a SG of 2.648.
Try using bromoform (SG 2.88). Silica will float and TeO2 will sink.
what about using HCl
TeO2 dissolves in HCl
but SiO2 not
If you want to make TeCl4, try HCL.
Separate names with a comma.
