In summary, TeO2 and SiO2 are two different oxides with distinct chemical compositions. They often occur together in natural minerals and need to be separated for industrial processes. This can be achieved through methods like leaching and fractional distillation. TeO2 is commonly used in optical and electronic devices, while SiO2 has a wide range of applications. However, caution must be taken when working with these substances as they can be hazardous if inhaled in large amounts.

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.
FAQ: Separating TeO2 from SiO2 - Chemistry Tips
What is the difference between TeO2 and SiO2?
TeO2 and SiO2 are both oxides, but they have different chemical compositions. TeO2 is composed of one atom of tellurium and two atoms of oxygen, while SiO2 is composed of one atom of silicon and two atoms of oxygen.
Why do we need to separate TeO2 from SiO2?
TeO2 and SiO2 often occur together in natural minerals and ores. Separating them is necessary for various industrial processes, as they have different properties and uses.
How is TeO2 separated from SiO2?
One common method is through leaching, where the mixture of TeO2 and SiO2 is treated with a solvent that selectively dissolves TeO2. Another method is through fractional distillation, where the mixture is heated to vaporize TeO2, which has a lower boiling point than SiO2.
What are some applications of TeO2 and SiO2?
TeO2 is commonly used in the production of optical and electronic devices, such as lenses and transistors. SiO2, on the other hand, has a wide range of applications, including in glassmaking, ceramics, and semiconductor production.
Are there any health or safety concerns when working with TeO2 and SiO2?
Both TeO2 and SiO2 can be hazardous if inhaled in large amounts. It is important to follow proper safety protocols, such as wearing protective gear and working in a well-ventilated area, when handling these substances.
