Influence of nano-sized aluminum oxide and polymer binder on the structure and mechanical properties of aluminum oxide-based composites
The influence of nano-sized Al2O3 (0-20%) and polymer binder (0-40%) on sintering, microstructure, and mechanical properties of composites based on micron-sized aluminum oxide was studied. It was found that the synergy of additives allows for a significant increase in the bending strength (up to 33 MPa) even with residual porosity. Optimal properties were shown by samples with 30-35% polymer and 10-20% nanophase, sintered at 1650-1700 °C.
