The bioactivity, i.e., bone-bonding ability, of 26 glasses in the system Na 2 O-K 2 O-MgO-CaO-B 2 O 3 -P 2 O 5 -SiO 2 was studied in vivo. This investigation of bioactivity was performed to establish the compositional dependence of bioactivity, and enabled a model to be developed that describes the

β¦ Synopsis
The liquidus surface structure and field of LiB 3 O 5 (LBO) primary crystallization have been revealed in Li 2 O-B 2 O 3 -MoO 3 ternary system. The optimization of charge composition and growth conditions results in large volume optical quality LBO single crystals yielding. Crystallographic properties and real defect structure of grown LBO single crystals have been investigated by X-ray powder diffraction method and X-ray reflection topography. The volume of the crystals is partly free of any structural imperfections.
