abstract = {This paper deals with the effect of hydroxylated boron nitride nanosheets (BNNS) incorporation on the microstructural and mechanical features of zirconia ceramics. Few-layered BNNS were synthesized via a simple
hydroxide-assisted planetary ball milling exfoliation technique. 3 mol% yttria tetragonal zirconia polycrystal
(3Y-TZP) with 2.5 vol% BNNS powders were prepared by an environmentally friendly process in water, and
spark-plasma sintered at three temperatures to explore the in-situ reduction of the functionalized BNNS. An
exhaustive study by (S)TEM techniques was performed to elucidate the influence of the sintering temperature on
the matrix and the 3Y-TZP/BNNS interfaces, revealing that BNNS were homogeneously distributed throughout
the matrix with an abrupt transition at 3Y-TZP/BNNS interfaces. BNNS effectively hindered slow crack growth,
thus increasing the composite’s crack growth resistance by about 30 %. A 1 MPa⋅m1/2 rising R-curve was also
induced by crack bridging.},
