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.

Hydroxyapatite Ceramic Hip Survey: Ceramic/Ceramic Bearings
Key Engineering Materials, 2007This paper describes the clinical application of alumina ceramic and, more recently, Zirconia Toughened Alumina (ZTA), to the bearing surfaces of hip implants with a maximum follow up of fifteen years. Patients are assessed pre- and post-operatively using the Harris Hip Score.

Ceramic materials have rapidly become the material of choice for indirect restorations. There are a variety of material types available for use such as feldspathic ceramics, glass ceramics and many types of zirconia. Advances in digital dentistry led to a rapid switch from porcelain fused to metal restorations to all-ceramic restorations. Variations in

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].

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.

A description of Quilcapampa’s ceramics in terms of paste, form, and iconography. The ceramics are divided into two broad groups. The first group relates to South coastal traditions, with the utilitarian ceramics coming from this group. The second group is Wari-related, coming from styles with origins from both the coast and highlands.

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.
