Boron nitride nanotubes ( BNNT s)/alumina composites were fabricated by hot pressing. The effect of BNNT s on the mechanical properties, including ambient and high‐temperature flexure strength and fracture toughness was investigated. As a result of sufficient physical and chemical bonding between BNNT s and alumina, the pullout and fracture of BNNT s concurrent with the suppression of BNNT s on abnormal growth of grains contributes to the excellent ambient and high‐temperature mechanical properties.
