Unidirectionally crystallized CaO‐P 2 O 5 glass‐ceramics were produced by reheating glass rods between 450° and 580°C (glass transition temperature ∼500°C) under a temperature gradient of 30°C/cm. These glass‐ceramics exhibit high bending strength (∼650MN/m 2 ) and toughness. Sample preparation is described and compared with conventional unidirectional solidification of melts. The characteristic mechanical properties are discussed in terms of the texture of the glass‐ceramics.
