Greatest Engineering Achievements of the 20th Century

Published on May 20th, 2009 | By: pwray@ceramics.org


The last century has seen an exponential explosion in engineering developments that would not have been possible without ceramics. The following list of the National Academy of Engineering’s Top 20 Engineering Achievements (www.greatachievements.org/) that have had the greatest impact on the quality of life in the 20th century shows how ceramic materials have made life easier for all humanity.


   Achievement

   How Ceramics Contribute:

 1. Electrification

Electrical insulators for power lines,

insulators for industrial/household

applications, glass light bulbs

 2. Automobile

Engine sensors, catalytic converters, spark plugs,

windows, engine components, electrical devices


 3. Airplane
