Fabrication and characterization of bioactive glass (45S5)/titania biocomposites

Assessment of nickel oxide substituted bioactive glass-ceramic on in vitro bioactivity and mechanical properties

“…This is attributed due to the reason that lighter element silicon has been replaced by heavier element nickel up by limited substitution of NiO from 0 to 1.65 mol% in the bioactive glass samples. The results show that more the flexural strength and micro hardness of base glass-ceramic and bioactive glass-ceramic substituted nickel oxide, the more would be the compactness of the structure of the glass [24,38]. By isotopic and isomorphic substitution of nickel, Smith et al [25] had shown that there were no appreciable difference in structural co-relation between 45S5 bioglass and NiO doped bioactive glass which indicated that addition of Ni 2+ ion would not adversely affect the overall bioactivity and structure of the glass.…”

Flame Spray Deposition of Titanium Alloy-Bioactive Glass Composite Coatings

“…In this process, powder particles are introduced into a high-temperature flame or plasma, where they are melted, accelerated, and deposited on a surface to produce a thin layered coating. Other studies have prepared composites of bioactive materials and titanium and its oxides through air plasma spraying (APS) (Ref 1, 10, 11) and high-velocity oxy-fuel (HVOF) spraying ( Ref 12,13). These studies found evidence of surface bioactivity in vitro.…”

In vitro bioactivity assessment and mechanical properties of novel calcium titanate/borosilicate glass composites

“…Among such materials it is possible to note inorganic composites consisting of stainless steel fibers embedded in a Bioglass 1 matrix [1], bioactive glass ceramic toughened by zirconia particles [5], hydroxyapatite/ diopside/alumina composite [6], bioactive glass (45S5)/titania composites [7], calcium titanate/titania coating composite [8], etc.…”
