Las formas cristalinas de Al2O3<\/a> son: \u03b1, \u03b3, \u03b7, \u03b4, \u03b8, \u03ba, \u03c7 y as\u00ed sucesivamente. Cuando cambian las condiciones externas, cambia la forma del cristal. En la variante Al2O3, como el ox\u00edgeno en \u03b1-Al2O3 (densidad 3,99g\/cm3) es el m\u00e1s compacto, s\u00f3lo \u03b1-Al2O3 (corind\u00f3n) es estable, y las dem\u00e1s formas cristalinas son inestables. Se transforma en \u03b1-Al2O3. Adem\u00e1s del corind\u00f3n, el tipo de cristal com\u00fan de Al2O3 debe ser \u03b3-Al2O3. El \u03b3-Al2O3 tiene estructura de espinela, pero en su estructura no se rellenan algunos huecos tetra\u00e9dricos, por lo que la densidad del \u03b3-Al2O3 (3,65 g\/ cm3) es menor que la del corind\u00f3n. Cuando se calienta Al(OH)3 para deshidratarlo, se forma \u03b3-Al2O3 a unos 450\u00b0C, y \u03b3-Al2O3 se calienta a una temperatura m\u00e1s alta para transformarse en corind\u00f3n. Sin embargo, la velocidad de transformaci\u00f3n ser\u00e1 m\u00e1s r\u00e1pida cuando el cambio sea superior a 1000?<\/p>\n

Tambi\u00e9n se forman otras formas cristalinas inestables de al\u00famina en distintas condiciones cuando se calienta y deshidrata el Al(OH)3. El \u03c1-Al2O3 es amorfo, pero hay quien piensa que es un estado de transici\u00f3n entre amorfo y cristalino. Dado que el \u03c1-Al2O3 es la \u00fanica forma de Al2O3 que puede hidratarse espont\u00e1neamente a temperatura ambiente, puede utilizarse como agente cementante para hormigones refractarios, por lo que ha recibido atenci\u00f3n en los \u00faltimos a\u00f1os.<\/p>","protected":false},"excerpt":{"rendered":"

The crystal forms of Al2O3 are: \u03b1, \u03b3, \u03b7, \u03b4, \u03b8, \u03ba, \u03c7 and so on. When the external conditions change, the crystal form will change. In the Al2O3 variant, since the oxygen in \u03b1-Al2O3 (density 3.99g\/cm3) is the most compactly packed, only \u03b1-Al2O3 (corundum) is stable, and other crystal forms are unstable.
