Die Kristallformen von Al2O3<\/a> sind: \u03b1, \u03b3, \u03b7, \u03b4, \u03b8, \u03ba, \u03c7 und so weiter. Wenn sich die \u00e4u\u00dferen Bedingungen \u00e4ndern, \u00e4ndert sich auch die Kristallform. Bei der Al2O3-Variante ist nur \u03b1-Al2O3 (Korund) stabil, da der Sauerstoff in \u03b1-Al2O3 (Dichte 3,99 g\/cm3) am dichtesten gepackt ist, w\u00e4hrend andere Kristallformen instabil sind. Umwandlung in \u03b1-Al2O3. Neben Korund sollte der h\u00e4ufigste Al2O3-Kristalltyp \u03b3-Al2O3 sein. \u03b3-Al2O3 hat eine Spinellstruktur, aber in seiner Struktur sind einige tetraedrische Hohlr\u00e4ume nicht gef\u00fcllt, so dass die Dichte von \u03b3-Al2O3 (3,65 g\/cm3) geringer ist als die von Korund. Wenn Al(OH)3 zur Dehydratisierung erhitzt wird, bildet sich \u03b3-Al2O3 bei etwa 450 \u00b0C, und \u03b3-Al2O3 wird auf eine h\u00f6here Temperatur erhitzt, um sich in Korund zu verwandeln. Die Umwandlungsgeschwindigkeit ist jedoch h\u00f6her, wenn die Temperatur\u00e4nderung mehr als 1000? betr\u00e4gt.<\/p>\n

Einige andere instabile Kristallformen von Aluminiumoxid bilden sich ebenfalls unter verschiedenen Bedingungen, wenn Al(OH)3 erhitzt und dehydriert wird. \u03c1-Al2O3 ist amorph, aber einige Leute denken, dass es ein \u00dcbergangszustand zwischen amorph und kristallin ist. Da \u03c1-Al2O3 die einzige Form von Al2O3 ist, die bei Raumtemperatur spontan hydratisieren kann, kann es als Zementierungsmittel f\u00fcr feuerfeste Gusserzeugnisse verwendet werden und hat daher in den letzten Jahren viel Aufmerksamkeit erhalten.<\/p>","protected":false},"excerpt":{"rendered":"
