Wikipedia says the formula of aluminum oxynitride is this $\ce{(AlN)_x·(Al2O3)_{1−x}}$, $0.30 \leq x \leq 0.37$ . What does this formula mean?

  • $\begingroup$ Go through Non-stoichiometric defects of Crystal Lattice , such as metal excess defects, metal deficiency defects etc. You may find your answer $\endgroup$

  • $\begingroup$ @Hark Have you been taught the simplest of on-stoichiometric defects? Forget the $x$, instead, do you understand what $\ce{Fe_{1.98}O}$ means? $\endgroup$ Mar 6, 2018 at 7:05
  • $\begingroup$ No i don't know about that $\endgroup$

    $\begingroup$ @OscarLanzi Oh, sorry. I was about to write $\ce{Fe_{0.98}O}$ to highlight the non-stoichiometric metal deficiency defect. I made a typo by mistake. $\endgroup$ Mar 7, 2018 at 1:37
