Alginate gelation is one of few methods that can produce porous ceramics with oriented tubular pores. This process allows the production of structured alumina, titania, and hydroxyapatite ceramics with an approximately honeycomb structure as demonstrated by the authors. The sizes of the capillaries can be adjusted by changing the material, the electrolyte, and the sintering temperature. Serial sectioning and automatic image analysis are suitable methods for investigating the capillary structure of the samples.
