Y2O3-doped Al2O3 transparent ceramics prepared by low temperature microwave sintering
Summary
Researchers successfully fabricated transparent alumina ceramics doped with Y2O3 using microwave sintering at lower temperatures than conventional methods, achieving finer grain sizes and superior optical and mechanical properties. The work demonstrates advantages of microwave sintering for producing high-performance ceramics.
AbstractY 2 O 3 -doped Al 2 O 3 transparent ceramics have been successfully fabricated by microwave sintering at the lowest temperature.Compared to vacuum sintering processing, the microwave sintering needs a lower sintering temperature and shorter dwelling time to get highly dense Y 2 O 3doped Al 2 O 3 transparent ceramics with finer grain size, higher mechanical and better optical properties.As a result, it is concluded that the low temperature microwave sintering has obvious advantages over the conventional sintering method in preparation of transparent Al 2 O 3 ceramics.

Effects of Grain Size and Humidity on Fretting Wear in Fine‐Grained Alumina, Al 2 O 3 /TiC, and Zirconia
This tribology study examined how grain size and humidity affect wear in ceramic materials (alumina and zirconia) under fretting conditions, finding that smaller grain sizes reduce wear through microplastic deformation of grain boundaries. This is a ceramics engineering study where 'microplastic deformation' refers to sub-yield material behavior, not environmental plastic particles.
