bioinert ceramics, like alumina and zirconia are used mainly for replacements of bones, hip joints and for dental implants. partially stabilized zirconia ceramics (psz or tzp with 3 mol.% or 5 wt.% y2o3), appear as perspective bioinert ceramics because of their high strength and corrosion resistance. in order to fabricate complex shapes, it is essential to use a near net shape processing like g...

Dielectric spectroscopy was applied to porous nanocrystalline Na0.5K0.5NbO3 (NKN) ceramic green body, wherein influences of percolation effect and water adsorption at pore surface of the ceramic green body on dielectric response were examined over wide temperature (150 to 450 K) and frequency (100 Hz to 1 MHz) ranges. Dielectric permittivity of the ceramic green body is about 2–3 orders of magn...

BACKGROUND Published literature reports significant improvements in pathological conditions, such as pain, blood dyscrasias, and cellulite, after using topical occlusive accessories containing particulate ceramic materials. Recent work reported a reduction in body measurements after 30 days of daily use of high-waist undershorts made of synthetic fabrics with embedded ceramic particles. OBJEC...

The effective shear and bulk viscosity, as well as dynamic viscosity, describe the rheological properties of the ceramic body during the liquid phase sintering process. The rheological parameters depend on the physical and thermo-mechanical characteristics of the material such as relative density, temperature, grain size, diffusion coefficient, and activation energy. Thermal behavior of the cer...

We are reporting a 25-year-old male, Egyptian ceramic worker, who presented to the Emergency Department of King Fahad University Hospital in Khobar, Saudi Arabia with a history of a ceramic piece which struck his right eye while working two days earlier. To our knowledge, this is the first case in literature, reporting an intralenticular ceramic foreign body.

BACKGROUND Therapeutic effects have been attributed to far-infrared (FIR) radiation emitted from different types of sources. One class of such infrared emitters consists of ceramics in a powdered form, which allows for its incorporation into creams and fabrics. Such ceramic materials emit in the FIR when subjected to body temperature. Published literature reports significant improvement in both...

We report a complication during total hip arthroplasty using an uncemented press-fit acetabular shell and ceramic liner for a woman with osteoarthritis. Fracture of the ceramic liner occurred during its insertion owing to non-concentric reduction. The main body of the ceramic liner became wedged in the acetabular shell and was resistant to removal. The shell itself was immovable owing to the pr...

The Centre for Fine Print Research at the University of the West of England has over five years experience in the 3D printing of ceramic materials. The first project undertaken was to investigate the use of 3D technologies for artists and resulted in the development of a patented ceramic body suitable for use in Z Corporation 3D printers. After bisque firing this material can be further process...

In this research, an ancient Iranian ceramic technology, which was published previously for the first time, has been used to produce various colored ceramic glazes.  The color of such ancient glazes was always blue and the suitable body for that is unique due to high quartz content. There is no report of other color productions in productive workshop and scientific publications. The basic purp...
