Novel Synthetic Route to Biomorphic Al2O3 Ceramics

Novel Synthetic Route to Biomorphic Al2O3 Ceramics

By using rattan palm as a biotemplate, highly porous, α‐Al2O3 ceramics with uniaxially directed porosity are produced via aluminum‐vapor infiltration and subsequent oxidation in air. The high‐strength ceramics retain the microstructural features of the palm (see Figure), and could be used as structu...

Zusammenfassung:By using rattan palm as a biotemplate, highly porous, α‐Al2O3 ceramics with uniaxially directed porosity are produced via aluminum‐vapor infiltration and subsequent oxidation in air. The high‐strength ceramics retain the microstructural features of the palm (see Figure), and could be used as structural supports in catalytic devices.
