The study of the alginate/hydroxyapatite composites structural properties
This paper describes the synthesis of sodium alginate/hydroxyapatite composites and the influence of the presence of Alg on HA crystallization. It was shown that the presence of Alg and the increase of its concentration leads to the decrease of the HA.
