  • Preparation of a Zirconia-Based Ceramic Membrane

    This work concerns the preparation of a mineral membrane by the slip casting method based on zirconium oxide (ZrO2) and kaolin. The membrane support is produced from a mixture of clay (kaolin) and calcium carbonate (calcite) powders using heat treatment (sintering). Membrane and support characterization were performed by Scanning Electron Microscopy (SEM), X-ray Fluorescence (XRF), …

  • Additive manufacturing of zirconia ceramics: a state

    2020-7-1 · Ebert et al. adopted the direct inkjet printing method to make the zirconia dental prostheses. A zirconia suspension was synthesized with 27 vol.% solid part, by which specimens with a characteristic strength of 763 MPa, and a mean fracture toughness of 6.7 MPa m 1/2 were achieved. It was indicated that this technique could be used to produce all-ceramic dental restorations with high accuracy ...
