Descrição geral

Hydroxyapatite is a key inorganic phosphate that has chemical and structural resemblance to bone. HAp is a popular biomaterial which finds use as a bone or teeth replacement and repair, hard tissue repair.

Aplicação

Hydroxyapatite(HAp) was used to model intracranial calcification in a study. HAp forms biocomposites with a number of polymers for various uses, such as:
  • for comparison purposes during the preparation of HAp based biocomposites with PVA and collagen.
  • for preparation of poly(methyl methacrylate) (PMMA)/hydroxyapatite (HA) by powder liquid method to manufacture denture base composites.
