Dataset language: English 2. Abstract: The dataset contains the results from transmission electron microscopy, particle size distribution, Raman spectroscopy and optical absorbance of Boron nitride nanosheet (BNNS) suspensions obtained by kitchen blender exfoliation at three rotor velocities. It also contains the results of the microstructural chracterization by scanning electron microscopy of spark plasma sintered ceramic composites with 3 mol% yttria tetragonal zirconia policrystal (3YTZP) matrix and different BNNS contents (1, 2.5 and 5 vol%), and their low temperature degradation study. 3. Keywords: Boron nitride nanosheets, yttria tetragonal zirconia, composite materials, low temperature degradation 4. Date of data collection: 01-06-2021 - 30-05-2024 5. Publication Date: 18-06-2025 6.

File list: File name: Dataset_BNNS_particle size, Raman, Ageing. xlxs Description: Excel file with several sheets: Two sheets are devoted to the analysis of the particle size distribution of BNNS suspensiosn obtained al low, medium and high velocities, obtained by two different techniques: - LG: Laser granulometry - DLS: Dynamic light scattering - Sheet "absorbance": optical absorbance spectra of the suspensions by UV-vis spectroscopy - Sheet "Raman": Raman spectrum of the nanosheets exfoliated at high rotor velocity. Two sheets are devoted to the analysis of the hydrothermal ageing behaviour of 3YTZP ceramic composites with 1, 2.5 and 5 vol% BNNS: - Ageing data: monoclinic volume fraction versus exposure time to ageing conditions. - KMAJ plots: linear plots of the transformed monoclinic fraction as a function of the ageing time File name: Microscopy images.zip Description: Zip file with two folders: - SEM composites: scanning electron microscopy (SEM) images of the 3YTZP composite with 2.5 vol% BNNS: BSE-SEM: Backscattered SEM of the polished cross-section surface Fracture: SEM image of the fracture surface - TEM BNNS: transmission electron microscopy of the BNNS exfoliated in kitchen blender 2.
