germane, tetrafluoro-, difluoride, diammonium salt - Introduction

Ammonium hexafluorogermanate is a chemical compound. Here are some basic information about ammonium hexafluorogermanate:

Property: Ammonium hexafluorogermanate is a colorless crystalline solid that is soluble in water. It has high stability at room temperature, but can decompose into hydrogen fluoride and gaseous germanium oxide at high temperatures.

Usage: Ammonium hexafluorogermanate is mainly used as an etchant in electronic devices, and can be used to etch small structures on silicon wafers to manufacture integrated circuits, display devices, etc. It can also be used to prepare other germanium compounds.

Method: A common method for preparing ammonium hexafluorogermanate is to react germanic acid and hydrofluoric acid with ammonium salts to form a precipitate of ammonium hexafluorogermanate. This reaction needs to be carried out under cooling conditions and attention should be paid to safety during operation.

Safety information: Ammonium hexafluorogermanate has certain corrosiveness and irritancy, and contact with skin and eyes may cause burns and irritation. During use and handling, it is essential to use personal protective equipment such as gloves, goggles, etc., and ensure that the operation is carried out in a well ventilated area. Avoid inhaling dust or solutions, and avoid mixing with acids, alkalis, and other substances. In case of accidental contact, rinse immediately with plenty of water and seek medical attention if necessary.
