Abstract

Highly textured, dense alumina ceramics were fabricated by a processing route which utilizes a mixture oral metal powder, alumina powder, alumina platelet (template) particles and a liquid phase former. The process involves dry forming the powder mixture (e.g., uniaxial pressing) to align the plate-like template particles. Texture quality can be controlled by compaction strain. Thermodynamic conditions favourable for template growth occur when the size ratio between the template thickness and matrix grains is ≥1.5.
