Abstract

<abstract abstract-type="main" id="jace12530-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Contrary to the moderate ballistic advantage of Al₂O₃<italic>ceramics</italic> over MgAl₂O₄ polycrystals, the present study shows a reverse ratio of the ballistic strength of alumina and spinel <italic>single crystals</italic>: Spinel single crystals outperform sapphire and exhibit a similarly high stability as submicrometer Al₂O₃ ceramics. The results correlate with different cleavage of single crystalline spinel and sapphire, changing the fragmentation on ballistic impact.</p> </abstract>
