Ceradyne, Incorporated, (NASDAQCRDN) is a Costa Mesa, California, USA, manufacturer of ceramics products. It is traded on the NASDAQ Stock Market.
In addition to producing ceramic components for industrial processes such as silicon foundries and ceramic fuel pellets for nuclear reactors, Ceradyne researches and produces varieties of ballistic armour for both personnel and vehicles.[3] The ceramic armor is lighter than regular steel plate armor facilitating greater mobility. As of September 16, 2007 the company was selling 25,000 sets of armor a month to the Pentagon.[4]
In December 2007, Ceradyne's lightweight armor was approved by the Army for use on military vehicles. Oshkosh Truck will produce the first of these armored vehicles using the armor on HEMETT crew cabs.[5] Ceradyne is also the producer of ceramic Enhanced Small Arms Protective Inserts (E-SAPI) for the US Army's Interceptor body armor, and the blast-proof components of the Ceradyne BULL MRAP/MMPV vehicle project.
In January 2008 the company also received an order for $9.6 million worth of body armor from UNICOR (Federal Prison Industries Inc.), which provides jobs and job training to inmates in US federal prisons.[5]

In October 2012 the company was purchased by 3M.

Product recall[edit]

In November 2012 thousands of SPEAR Generation III ballistic armor plates manufactured by Ceradyne for issue to United States Special Operations troops were recalled due to "safety defects". An analysis by the Department of Defense discovered the flawed plates. Defects were identified in less than five percent of plates tested according to United States Special Operations Command (USSOCCOM). USSOCCOM says "No one has been killed or wounded as a result of the defective body armor".[6][7]
