APPLICATION
1.Main?ingredient?of?Ruby?and?Sapphire?are?alumina,?because?of?other?impurities?present?different?color.?Ruby?red?contains?chromium?oxide,?the?sapphire?blue?containing?iron?oxide?and?titanium?dioxide.
2.Alumina?is?the?reason?of?aluminum?can?not?easily?be?corrosion?in?the?air.This?layer?of?aluminum?oxide?film?to?prevent?aluminum?oxidation.?This?thickness?and?properties?of?oxide?film?can?be?strengthened?accessed?through?anodized?.
3.Aluminum?is?a?good?conductor?of?electricity?and?heat,?but?alumina?is?insulator?of?electrical?and?thermal.?Corundum?with?high?hardness,?suitable?for?use?as?abrasive?and?cutting?tools.
4.Alumina?powder?usually?as?the?medium?of?chromatographic?analysis.
5.In?August?2004,?scientists?in?the?U.S.?company?3M?developed?transparent?alumina?called?tempered?glass?,use?aluminum?and?rare?earth?elements?manufactured?synthetic?alloy.
6.Can?be?used?as?emergency?brakes?of?high-speed?train.
7.Porous?high?surface?area?alumina?known?as?activated?alumina,?commonly?used?as?a?catalyst,?adsorbent,?dehydrating?agent?and?catalyst?carrier.
