Microstructural characterization of sodium niobates by the sol-gel process for use in tissue engineering
Sodium niobate is a potentially important dielectric material for its piezoelectric properties. It has a perovskite-like structure, in its most stable form. Recent advances in tissue engineering have focused on the use of biochemical and physicochemical signals to trigger specific cellular responses...

| Resumo: | Sodium niobate is a potentially important dielectric material for its piezoelectric properties. It has a perovskite-like structure, in its most stable form. Recent advances in tissue engineering have focused on the use of biochemical and physicochemical signals to trigger specific cellular responses and encourage better biological interaction between the biomaterial and living tissue. Piezoelectric ceramics may be the key to the functionalization of current grafts, as they exhibit mechanically generated electrical behavior. In this work, the production of sodium niobate (NaNbO3), a piezoelectric biomaterial, in different molar compositions, by the sol-gel method was adopted in order to observe the changes in the microstructure using scanning electron microscopy (SEM) techniques. The synthesis was efficient, and the microstructure is in agreement with what was found in the literature. |
