Purpose – Zirconia ceramics exhibit high strength and fracture toughness. The purpose of this paper is to research a possibility of crack healing in zirconia ceramics.
Design/methodology/approach – ZrO
Findings – The paper finds that ZrO
Research limitations/implications – The paper provides a low temperature healing and a new mechanism of crack healing.
Originality/value – The paper shows the healing temperature and the minimum time required to heal showed a good proportional relation on the Arrhenius plot at temperatures of 600-800°C. Moreover, the crack healing is caused by SiO
