Development of SiO2 – Li2O – P2O5 – ZrO2 dental glass-ceramic systems with extended lifetimes: crystallization mechanisms and resistance to subcritical crack growth
(Third Party Funds Group – Sub project)
Overall project: Dental glass-ceramic in the system SiO2 – Li2O – P2O5 – ZrO2
Term: since 1. July 2021
Funding source: Deutsche Forschungsgemeinschaft (DFG)Classes of materials that resemble natural teeth, such as polycrystalline ceramics, glass-ceramics and ceramic-methacrylate composites, have been preferred for tooth replacement for some time.
The first commercial product was based on a non-stoichiometric multi-component SiO2-Li2O-Al2O3-K2O-P2O5-ZrO2-ZnO system that was pre-crystallised, then melted and injected into a mould made of refractory material. The resulting glass-ceramics reached a degree of crystallisation of ~70 vol% with elongated Li2Si2O5 crystallites exhibiting very good mechanical properties.
The research approach makes it possible to determine relationships between the mechanical properties, composition and microstructure, either in the glass-ceramic or in the residual glass.
For this purpose, the influence of the SiO2/Li2O molar ratio on the crystallisation behaviour of Li2SiO3 and Li2Si2O5 phases is analysed and the effect of ZrO2 addition at constant SiO2/Li2O ratio on crystallisation kinetics and network structure of the residual glass is investigated.
