V\u010faka t\u00fdmto vlastnostiam je oxid hlinit\u00fd ide\u00e1lnym materi\u00e1lom na pou\u017eitie vo vysokov\u00fdkonn\u00fdch aplik\u00e1ci\u00e1ch vr\u00e1tane v\u00fdroby elektrickej energie a jadrovej energie. Okrem toho ho jeho odolnos\u0165 chr\u00e1ni pred po\u0161koden\u00edm v d\u00f4sledku n\u00e1razu, kor\u00f3zie alebo p\u00f4sobenia chemick\u00fdch l\u00e1tok.<\/p>\n
