Evaluation of the ceramic/ceramic interface
American Journal of Orthodontics and Dentofacial Orthopedics, 1994The purpose of this study was to investigate bond strength for ceramic orthodontic brackets bonded to dental porcelain. The following factors were tested. Two types of ceramic brackets were placed on two different types of porcelain surfaces with two different bonding systems.

Alumina ceramic is a highly oxidized ceramic that is formed by the fusion of microscopic grains of alumina (Al2O3) and/or zirconia (ZrO2) ceramic powder into a solid phase. During the process of sintering known as “hot isostatic pressing,” the agents are pressed above 1000 bars and sintered at 1600 °C [1].

Wetting of ceramic-metal and ceramic-ceramic interfaces
[Proceedings] 1990 IEEE 7th International Symposium on Applications of Ferroelectrics, 2002Contact angles of the metal-ceramic interface in a heating process were measured until the metal melted. Ag on BaTiO/sub 3/ disks melted with an almost hemispherical shape at an obtuse angle and did not wet to BaTiO/sub 3/. Metal Ag on superconducting Ba/sub 2/Y/sub 1/Cu/sub 3/O/sub 7- delta / showed better wetting than in the case of BaTiO/sub 3 ...

Ceramics and ceramic-to-metal sealing
Vacuum, 1964Abstract The physical characteristics of ceramics most commonly used in the electronic and aerospace industry are described, and a review is presented of the methods by which ceramics are joined to metals to arrive at vacuum-tight, reliable structures. The subject of bond mechanisms is touched briefly, and some data on voltage breakdown are given.

Gel technology in ceramics, glass-ceramics and ceramic-ceramic composites
Ceramics International, 1989Abstract For many years, ceramists have been interested in sintering at low temperatures to manufacture devices that incorporate different materials sintering together, to deposit films on a substrate, to make fibers or ceramic-ceramic composites and to achieve fine-grained microstructures.

Ceramic-on-Ceramic Total Hip Arthroplasty
The Journal of Arthroplasty, 2009Ceramic bearing surfaces have been introduced to prevent bone loss after osteolysis seen with conventional polyethylene bearing surfaces. One hundred three ceramic-on-ceramic total hip arthroplasties in 97 patients were retrospectively reviewed. Average follow-up was 50.4 months.

Ceramic/ceramic total hip arthroplasty
Journal of Orthopaedic Science, 2000Alumina-on-alumina total hip arthroplasty has been used for 30 years, mainly in Europe. The theoretical advantages of this combination are represented by its remarkable sliding characteristics, its very low wear debris generation, and its sufficient fracture toughness.

Bonding and Structure of Ceramic-Ceramic Interfaces
Physical Review Letters, 2013Quantum molecular dynamics simulations of α-Al2O3(0001)/3C-SiC(111) interfaces reveal profound effects of thermal annealing for producing strong interfaces consisting solely of cation-anion bonds and their consequence on interfacial structures. A Si-terminated SiC surface and Al2O3 form a stronger interface (Si-interface) with a Si-O bond density of 12.

Brazing of ceramic-to-ceramic and ceramic-to-metal joints in air
Frontiers of Mechanical Engineering in China, 2010Reactive air brazing (RAB) is an emerging technology for the production of ceramic-to-ceramic and ceramic-to-metal joints. In this study, RAB was investigated with respect to the potential applications for solid oxide fuel cells (SOFCs) as one example of use. It was found that alumina could be well brazed by RAB with AgCu and AgCuTi brazes.

Microwave Sintering of Metal-Ceramic and Ceramic-Ceramic Composites
MRS Proceedings, 1994ABSTRACTPolyphase ceramic and metal ceramic composites with at least one high dielectric loss component are potential candidates for application of microwave sintering, because of the high effectiveness of power dissipation and short sintering times.
