Sinterability of calcium phosphate through rapid sintering

Development of dense nanostructured hydroxyapatite (HA) with the major concern to enhance densification while limiting its grain growth has received great demand. This is due to inherent brittleness and lower mechanical strength of HA ceramic. A promising way to obtain this could be a fabrication of...
