“…The compactness characteristics of sintered samples were evaluated according to Archimedes' principle [29][30][31][32][33] by weighing each sample in both air and water in a specific equipment (Precisa hydrostatic balance) using the immersion test. This test was carried out on each forsterite ceramic to determine the relative and apparent (bulk) density as well as total and apparent porosity.…”

“…For this purpose, three input data are needed, namely the mass of dried sample in air, m0, the mass of sample immersed in water, m1, and the mass of sample saturated with water (i.e. sample with free bubbles on its surface), but determined in air, m2 [31][32]. To increase the accuracy of the immersion mass and of saturated mass, it is recommended that each sample should be kept in boiling water for at least 2 h, before the immersion test.…”

“…To increase the accuracy of the immersion mass and of saturated mass, it is recommended that each sample should be kept in boiling water for at least 2 h, before the immersion test. The reason is related to the fact that boiling water can better penetrate both the pores and the structural holes within the sample [31].…”

This study is aimed to evaluate the biocompatibility and bioactivity of some new porous forsterite ceramics (FCs) produced from high-purity nano forsterite powder, synthesized by an original sol-gel method, which was subjected to pressing into pellets, by using a poly vinyl alcohol solution as a binding component. Then, the raw pellets were sintered at 1200 �C, 1300 �C, 1400 �C and 1450 �C. The obtained four forsterite ceramics, FC-1200, FC-1300, FC-1400 and FC-1450, were fully characterized by density, porosity and shrinkage measurements. The forsterite ceramics exhibited excellent biocompatibility determined by an in vitro cell viability assay, such as MTT test. Furthermore, the in vitro bioactivity test was performed by immersing the forsterite ceramics into simulated body fluid (SBF) and examining the hydroxyapatite (HAP) formation on forsterite ceramics, as evidenced by XRD, FTIR, SEM with EDX. Moreover, the relationship between porous structure and bioactivity of forsterite ceramics in SBF as well as the performance of FC in a cell culture was evaluated. The findings strongly recommend these forsterite ceramics for biomedical applications, as potential bone substitutes.
