Enhanced mechanical properties of hBN-ZrO composites and their biological activities on : synthesis and characterization.

In this study, six compositions in the system [(h-BN)-(100 - )ZrO] (10 ≤ ≤ 90) were synthesized by a bottom up approach, , the solid-state reaction technique. XRD results showed the formation of a novel and main phase of zirconium oxynitrate ZrO(NO) and SEM exhibited mixed morphology of layered and stacked h-BN nanosheets with ZrO grains. The composite sample 10 wt% h-BN + 90 wt% ZrO (10B90Z) showed outstanding mechanical properties for different parameters, , density (3.

Synthesis and 3D Interconnected Nanostructured h-BN-Based Biocomposites by Low-Temperature Plasma Sintering: Bone Regeneration Applications.

Recent advances and demands in biomedical applications drive a large amount of research to synthesize easily scalable low-density, high-strength, and wear-resistant biomaterials. The chemical inertness with low density combined with high strength makes h-BN one of the promising materials for such application. In this work, three-dimensional hexagonal boron nitride (h-BN) interconnected with boron trioxide (BO) was prepared by easily scalable and energy efficient spark plasma sintering (SPS) process.

Zirconia based dental ceramics: structure, mechanical properties, biocompatibility and applications.

Zirconia (ZrO) based dental ceramics have been considered to be advantageous materials with adequate mechanical properties for the manufacturing of medical devices. Due to its very high compression strength of 2000 MPa, ZrO can resist differing mechanical environments. During the crack propagation on the application of stress on the surface of ZrO, a crystalline modification diminishes the propagation of cracks.
