What is Al3N4? Important Knowledge About Al3N4

  1. Definition of Al3N4

    Al3N4, also known as aluminum nitride, is a colorless solid that is extremely hard and insoluble in water. In English, it is called Aluminum nitride. Al3N4 has a molecular weight of 101.96 g/mol. It consists of 3 atoms of aluminum (Al) and 4 atoms of nitrogen (N), which together form a molecule of Al3N4. In terms of ionic composition, Al3N4 has 3 aluminum ions Al3+ and 4 nitrogen ions N3-.

  2. Properties of Al3N4

    2.1 Physical properties of Al3N4: Al3N4 is a solid in its natural form, colorless and odorless. It is insoluble in water, and its pH level is undefined as it does not dissolve in water.

    2.2 Chemical properties of Al3N4: Al3N4 is very unreactive with most substances. It only reacts with strong, hot HF acid.

  3. Common chemical equations for Al3N4:

    Al3N4 does not easily react with metals, acids, non-metals, or salts. Some reactions may occur, but they require very stringent conditions such as high temperature or high pressure.

  4. Synthesis of Al3N4

    4.1 Laboratory synthesis of Al3N4: currently, there is no method to synthesize Al3N4 in the laboratory.

    4.2 Industrial synthesis of Al3N4: Al3N4 is typically produced industrially by heating aluminum in nitrogen gas at high temperatures.
