AMMONIUM FLUORONIOBATE - Introduction
Ammonium hexafluorobiate is an inorganic compound whose chemical formula is NH4NbF6. The following is a description of the properties, uses, preparation and safety information of ammonium hexafluorobiate:
Nature:
1. Appearance: Hexafluoroammonium niobate is colorless crystalline or white crystalline powder.
2. melting point: its melting point is about 460 degrees Celsius.
3. solubility: soluble in water, acid and some organic solvents.
Use:
1. Ammonium hexafluorobiate is mainly used as a staining agent for electron microscope samples to enhance the contrast of samples.
2. It is also used to prepare niobium compounds and other niobate compounds, and is used in the fields of electronics and ceramic industry.
Method:
The preparation of ammonium hexafluorobiate generally involves the following steps:
1. First, hexafluoroniobic acid (NbF6) is prepared by reacting niobic acid (Nb2O5) with hydrofluoric acid or ammonium fluoride.
2. Then, hexafluoroniobic acid is reacted with ammonia water or ammonia gas to finally obtain ammonium hexafluoroniobate.
Safety Information:
1. Ammonium hexafluorobiobate is a corrosive compound and should be avoided in contact with skin and eyes.
2. Wear suitable protective gloves, goggles and protective clothing during handling, handling and storage.
