The in-vitro behaviour of three series of dense materials with different crystallization degree and phases produced by Spark Plasma Sintering (SPS) from CaO-rich bioglass powders is investigated by soaking them up to 14 days in Simulated Body Fluid (SBF). The completely amorphous materials produced after 2 min at 730 °C display the more pronounced substrate-solution interaction. This is highly beneficial for the rapid generation (< 3 days) of an apatite layer on the substrate surface. Larger amounts of such phase are also produced during the entire immersion period. These characteristics are moderately mitigated when 80 wt.% of the glass is crystallized at 850 °C with the main formation of α-CaSiO₃. Nonetheless, more severe SPS conditions (1000 °C, 20 min) lead to specimens rich of β-CaSiO₃ that still retain 12 wt.% of the amorphous nature while scarcely interact with SBF. The apatite formation is correspondingly delayed (7 days) and its amount significantly decreased.

在体外的三个系列与由选自CaO富含生物玻璃粉末放电等离子烧结（SPS）产生的不同结晶度和相致密材料的行为是由在模拟体液（SBF）将它们浸泡长达14天研究。在730°C下放置2分钟后生成的完全非晶态材料显示出更明显的底物与溶液的相互作用。这对于在基材表面上快速生成（<3天）磷灰石层非常有利。在整个浸没期间还会产生大量的这种相。当80重量％的所述玻璃的％的在850℃下与主形成的α-卡西欧结晶这些特性适度减轻₃。然而，更严重的SPS条件（1000℃，20分钟）导致的富β标本-CASIO ₃仍然保持无定形性质的12重量％，而几乎不使用SBF相互作用。磷灰石的形成相应延迟（7天），其数量显着减少。
