Hexafluorosilicic acid
CAS 16961-83-4
Alias：SILICOFLUORICACID;SYSMEHFRWGKPVGKKRRPVKVYPNGAEDESAEAFPLEF;PHEHUMAN;HYDROGENHEXAFLUOROSILICATE;HYDROFLUOROSILICICACID;HYDROFLUOSILICICACID;HYDROSILICOFLUORICACID
Molecular formula：F6H2Si
Molecular weight：144.09
Structural formula：
1.Performance and use
Hexafluorosilicic acid is the basic raw material for the production of sodium, potassium, ammonium, magnesium, copper, barium, lead, other fluorosilicates, and silicon tetrafluoride. Used for metal electroplating, wood preservation, beer disinfection, disinfection of brewing industry equipment (1%~2% H2SiF6), and electrolytic refining of lead. It is also used as a mordant and metal surface treatment agent. Used as an analytical reagent for the determination of barium, separation of barium and strontium.
2.Technical indicators
Testing Items | Standard Requirements | Testing Result |
Color | Colorless transparent liquid | Qualified |
Content |
≥40.0% |
Qualified |
Free acid | ≤0.5% | Qualified |
3. Packaging and storage
Packaging specification: 190kg/drum，which can also be determined according to user needs
During transportation, it is necessary to protect against sunlight, rain, and high temperatures.
The product should be stored in a cool, dark, ventilated place, away from sources of fire.
4. Safety protection
Pay attention to labor protection when handling it and avoid contact with skin, eyes, etc.
After contact, rinse immediately with plenty of water
