Silicon nitride (Si3N4) is a promising biomaterial, currently used in spinal fusion implants. Such implants should result in high vertebral union rates without major complications. However, pseudarthrosis remains an important complication that could lead to a need for implant replacement. Making silicon nitride implants more bioactive could lead to...

... 2 shows that minuscule amounts of sodium were detected on the surfaces of bulk samples. Looking at the atomic concentrations of the surfaces of all groups (Table 1), the thermally treated samples stand out. It is clear that a layer of silicon dioxide was formed, while a very small amount of nitrogen remained present on the surface of the material, as expected from the literature [38]. ...
