What is it about?
Natural HA has been extracted from bovine bone by using a mechanical-thermal method and calcination at 800 ◦C resulting in relatively high purity HA with the Ca/P ratio is 1.61, that is very close to the Ca/P pure HA (1.67). The addition of alumina to the HA composite products does not change the ratio of Ca/P, but it can reduces effectively the agglomeration percentage and then improves significantly the mechanical properties with a maximal ratio of 50 % HA, 50 % alumina, and 30 % resin (or equivalen to 10 g HA, 10-g alumina, and 6-g resin in this study).

Why is it important?
Hydroxyapatite (HA) is synthesized from the bovine bone waste using a mechanical-thermal method and calcination at 800 ◦C. Effects of alumina concentration on mechanical properties of HA-alumina are thoroughly analyzed. The addition of 50 % alumina into HA provides the highest hardness and tensile strength of the HA-alumina composite.
Perspectives
I hope this article can provide added value in the use of biogenic waste to preserve the environment and at the same time to support the SDs program.
