Verfahren zur Herstellung eines Implantates

Implant bodies are mfd. by placing ceramic powder inside a 3-D changeable mould, and compacting the powder in the mould prior to subjecting to cold isostatic pressing. The green body produced is removed from the mould and its dimensions are such that after undergoing sintering, the shrinkage caused...

More Information
Summary:Implant bodies are mfd. by placing ceramic powder inside a 3-D changeable mould, and compacting the powder in the mould prior to subjecting to cold isostatic pressing. The green body produced is removed from the mould and its dimensions are such that after undergoing sintering, the shrinkage caused produces a body with the required final dimensions.
