“…In this work, spherical granules obtained by suspension technology [5] from synthetic ceramic powders with a variable content of HA and WT [6] (80/20, 60/40, 40/60 or 20/80 wt.% HA and WT, respectively) and gelatine (a binder polymer) were investigated. Gravimetric analysis of materials was performed using a muffle furnace «EKPS-5» (Smolensk SKTB SPU).…”

Control of the composition after heat treatment is important stage of biomaterials production especially in case of their new versions creation, because many biocompatible synthetic substances are unstable at high temperatures. Interaction between components in multicomponent systems is possible with the formation of new undesirable products. In this work, the process of calcination of composite granules with a variable content of hydroxyapatite and wollastonite and binder polymer (gelatine) was studied. It was found that materials heat treatment leads to a change of their phase composition caused by the apatite decomposition, transition of β-CaSiO3 to α-form, and calcium silicophosphate formation (in samples where apatite is the main component). Calcined products composition depends on the apatite/wollastonite ratio in the materials.

“…In this work, granules were synthesized by the suspension technology [10]. Synthetic ceramic powders with a variable content of hydroxyapatite and wollastonite (WT, CaSiO 3 ) [11] were used in the granules synthesis. A weighed portion of the powder with HA/WT mass ratio 80/20, 60/40, 50/50, 40/60, 20/80 or 0/100 was mixed with a given volume of 10% gelatine water solution, thoroughly stirred and this suspension was dropped into a container with vegetable oil, stirred with a magnetic stirrer.…”

Spherical granules are one of the preferred forms of biomaterials for bone defects healing. Chemical composition and microstructure of these materials are largely determines their behavior in vivo. Synthesis and properties investigation of polydispersed porous composite granular materials containing several bioactive components are the important task of modern biomedical chemistry. In this work, the microstructure of organomineral granules based on hydroxyapatite, wollastonite, and gelatine, and the products of their calcination were studied. It was found that as a result of removal of the polymer binder from the ceramic particles surface, nanopores were disclosed, and the subsequent crystallites sintering provide the granules shape stability.
