In lighting, translucent aluminium oxide is used in some [[sodium vapor lamp]]s.<ref>{{cite web|url=http://www.ge.com/innovation/timeline/eras/science_and_research.html|title=GE Innovation Timeline 1957–1970|access-date=2009-01-12| archive-url= https://web.archive.org/web/20090216233917/http://www.ge.com/innovation/timeline/eras/science_and_research.html| archive-date= 16 February 2009 | url-status= live}}</ref> Aluminium oxide is also used in preparation of coating suspensions in [[compact fluorescent lamp]]s.

In chemistry laboratories, aluminium oxide is a medium for [[chromatography]], available in [[Base (chemistry)|basic]] (pH&nbsp;9.5), [[acid]]ic (pH&nbsp;4.5 when in water) and neutral formulations. Additionally, small pieces of aluminium oxide are often used as [[boiling chips]].

Health and medical applications include it as a material in [[hip replacement]]s<ref name="azom" /> and [[Oral contraceptive pill|birth control pills]].<ref>{{Cite web|url=https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=75bb0024-8f1a-4036-9acd-006ea430f3b7#|title=DailyMed - JUNEL FE 1/20- norethindrone acetate and ethinyl estradiol, and ferrous fumarate|website=dailymed.nlm.nih.gov|access-date=2017-03-13|url-status=live|archive-url=https://web.archive.org/web/20170313130132/https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=75bb0024-8f1a-4036-9acd-006ea430f3b7|archive-date=2017-03-13}}</ref>

and [[dosimeter]] for radiation protection and therapy applications for its [[optically stimulated luminescence]] properties.{{citation needed|date=August 2014}}

Insulation for high-temperature furnaces is often manufactured from aluminium oxide.  Sometimes the insulation contains a percentage of silica depending on the temperature rating of the material.  The insulation can be made in blanket, board, brick and loose fiber forms for various application requirements.

It is also used to make [[spark plug]] [[insulator (electricity)|insulator]]s.<ref>{{Cite book|url=https://archive.org/details/aluminiumtheeleme00john|url-access=registration|page=[https://archive.org/details/aluminiumtheeleme00john/page/19 19]|quote=Aluminium oxide is also used to make spark plug insulators.|title=Aluminium|last=Farndon|first=John|date=2001|publisher=Marshall Cavendish|isbn=9780761409472|language=en}}</ref>

Using a [[Plasma spraying|plasma spray]] process and mixed with [[Titanium dioxide|titania]], it is coated onto the braking surface of some [[bicycle]] rims to provide abrasion and wear resistance.{{Citation needed|date=March 2011}}
 
Most ceramic eyes on fishing rods are circular rings made from aluminium oxide.{{citation needed|date=August 2014}}

In its finest powdered (white) form, called Diamantine, aluminium oxide is used as a superior polishing abrasive in watchmaking and clockmaking.<ref>{{Cite book | title=Practical Watch Repair|pages=164 | last=de Carle|first=Donald|publisher=N.A.G.

Aluminium oxide is also used in the coating of stanchions in the motocross and mountain bike industries. 
This coating is combined with [[molybdenum disulfide]] to provide long term lubrication of the surface.<ref>{{Cite web|url=http://www.kashima-coat.com/global/service/kashima-coat/|title = Kashima Coat - Products / Services &#124; Next-generation anodize boasting light weight, high lubrication, and superb wear resistance.
