Fabrication of Microstructure-controlled Advanced Ceramics by External Field-applied Colloidal Processing

Colloidal Processing of Ceramics

Colloidal processing of ceramics is reviewed with an emphasis on interparticle forces, suspension rheology, consolidation techniques, and drying behavior. Particular attention is given to the scientific concepts that underpin the fabrication of particulate-derived ceramic components. The complex interplay between suspension stability and its structural evolution during colloidal processing is h...

Ceramics overview: classification by microstructure and processing methods.

The plethora of ceramic systems available today for all types of indirect restorations can be confusing--and overwhelming--for the clinician. Having a better understanding of them is key. The authors use classification systems based on the microstructural components of ceramics and the processing techniques to help illustrate the various properties and uses.

Fibrous Monolithic Ceramics: I , Fabrication, Microstructure, and Indentation Behavior

Monolithic ceramics have been fabricated from coated green fibers to create fibrous microstructures. The fibrous monoliths consist of high aspect ratio polycrystalline regions (cells) of a primary phase separated by thin secondphase regions (cell boundaries) designed to improve fracture resistance. The cells are the remnants of the green fiber which consists of ceramic powder and a polymer bind...

Composite Laser Ceramics by Advanced Bonding Technology

Composites obtained by bonding materials with the same crystal structure and different chemical compositions can create new functions that do not exist in conventional concepts. We have succeeded in bonding polycrystalline YAG and Nd:YAG ceramics without any interstices at the bonding interface, and the bonding state of this composite was at the atomic level, similar to the grain boundary struc...
