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 ...

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.

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.

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.
