Ceramic on Ceramic

2018
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].

Ceramic-on-Ceramic Total Hip Arthroplasty

The Journal of Arthroplasty, 2009
Ceramic 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.

Gel technology in ceramics, glass-ceramics and ceramic-ceramic composites

Ceramics International, 1989
Abstract 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.

Microwave Sintering of Metal-Ceramic and Ceramic-Ceramic Composites

MRS Proceedings, 1994
ABSTRACTPolyphase 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.

Ceramic pigments for construction ceramics [PDF]

Glass and Ceramics, 2009
The possibility of synthesizing ceramic pigments using industrial wastes — nepheline sludge from the production of alumina, spent sulfovanadate diatomite (SVD) catalyst, and spent Ziegler – Natt catalyst—is studied. These materials will lower production costs of ceramic pigments.

Ceramics and ceramic-to-metal sealing

Vacuum, 1964
Abstract 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.

Ceramic/ceramic total hip arthroplasty

Journal of Orthopaedic Science, 2000
Alumina-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.

Ceramic and glass-ceramic lasers

Annales de Chimie Science des Matériaux, 2003
Les materiaux ceramiques actives par des ions luminescents se revelent etre des substituts prometteurs des monocristaux comme source laser, grâce notamment a une synthese moins difficile et une capacite de dopage accrue. Bien que ces materiaux ceramiques soient synthetises depuis les annees 60, ce n'est que recemment qu'ils sont devenus vraiment ...

Ceramics

2023
This chapter deals with the additive manufacturing (AM) techniques utilized to produce technical ceramics. We then exclude those ceramics utilized for building, sanitary ware, art, and thermal insulation. The chapter starts with a description of the technical ceramics to date available for AM, their main characteristics, and applications.

Microcracking in Ceramic/Ceramic Composites

Advanced Ceramic Materials, 1988
A technique was developed to detect the onset, size, evolution, and anisotropy of surface microcracks in ceramic composite materials as a function of applied stress. The method is based on measuring the electrical resistance changes of a thin gold film sputtered on the surface of the composite as a function of stress.
