The Case for Colloidal Silica
Learn about colloidal silica’s diverse range of uses in research and in industry through this exclusive eBook written in collaboration with the American Chemical Society and C&EN magazine.
These nanoscale particles of amorphous silica boast a range of attributes – such as high stability, hardness and excellent binding ability – thanks to the tunable chemistry of the particles’ silanol-rich surface. Applications for colloidal silica now range from metal-casting molds to drug-resistant bacterial biofilms. Grace welcomes the opportunity to highlight these diverse developments, which are broad in scope yet are all built on the same strong foundation of colloidal silica chemistry.
Concepts explained and featured in this eBook:
- Learn about colloidal silica’s many chemical and physical attributes
- Gain insight into how colloidal silica gets used in investment casting, a major application for the material, and improves catalyst performance for industrial applications
- Discover how researchers are using colloidal silica to address pressing biomedical problems
