*Ammonium hydrogen difluoride

Here is the detailed introduction to ammonium bifluoride (CAS number: 1341 - 49 - 7) in English:

Basic Information

• English Name: Ammonium Bifluoride or Ammonium Hydrogen Fluoride
• Chemical Formula: NH?HF?
• Molecular Weight: 57.04

Physicochemical Properties

• Appearance: Colorless transparent to white crystalline powder or lump, slightly sour.
• Melting Point: 125.6 °C
• Boiling Point: 230 °C
• Density: 1.50 g/cm³
• Solubility: Soluble in water, the aqueous solution is acidic. It can be dissolved in alcohol and is insoluble in liquid ammonia.

Stability and Reactivity

• Stability: It is stable under normal temperature and pressure, but it will absorb moisture and release hydrogen fluoride gas in humid air.
• Incompatible Substances: Acids, bases, active metal powders, flammable or combustible substances, etc. Contact with these substances may cause violent reactions and even pose risks.

Uses

• Etchant: In the electronics industry, it is often used to etch glass, silicon wafers, etc., which can accurately treat the material surface to meet the needs of electronic component manufacturing. For example, it is used to etch glass substrates in the manufacture of liquid crystal displays.
• Preservative: It can be used as a preservative for wood and other materials, which can effectively prevent wood from being eroded by microorganisms and prolong the service life of wood.
• Flux: In the metallurgical industry, it is used as a flux, which can reduce the melting point of ores and promote the extraction and refining process of metals.
• Chemical Raw Material: It is an important raw material for the preparation of other fluorides. Through reactions with other compounds, a variety of fluorine - containing chemicals can be synthesized, which are widely used in the fields of medicine, pesticides, dyes, etc.
