In vitro degradation and cell response of calcium carbonate composite ceramic in comparison with other synthetic bone substitute materials

Materials Science and Engineering: C, 2015
The robust calcium carbonate composite ceramics (CC/PG) can be acquired by fast sintering calcium carbonate at a low temperature (650 °C) using a biocompatible, degradable phosphate-based glass (PG) as sintering agent. In the present study, the in vitro degradation and cell response of CC/PG were assessed and compared with 4 synthetic bone substitute ...

Estimating the erosion and degradation performance of ceramic and polymeric insulator materials in high current arc environments

IEEE Transactions on Magnetics, 1991
Modeling the erosion and holdoff degradation performance of various commercially available polymeric and ceramic insulators is addressed. The insulators are tested on a surface discharge switch at approximately 300 kA in atmospheric air. Test diagnostics include the surface voltage holdoff recovery and the eroded mass loss of the insulator and ...

Long-term thermal/chemical degradation of ceramic candle filter materials

2014
Commercial ceramic candle filters were exposed to harsh environments to determine the effects of alkali and steam on their long-term durability. Ceramic candle filters are composed of relatively coarse aggregates fixed by a ceramic bond. The filters studied include a clay-bonded, granular aluminosilicate candle and three types of clay-bonded, granular ...

dc-Electrical Degradation of the BT-Based Material for Multilayer Ceramic Capacitor with Ni internal Electrode: Impedance Analysis and Microstructure

Japanese Journal of Applied Physics, 2001
The impedance of a BaTiO3 (BT)-based multilayer ceramic capacitor with a nickel internal electrode (Ni-MLCC) was investigated by measuring the frequency domain at various temperatures. All the obtained impedance data could be successfully fitted to a 4-RC section electrical equivalent network.

Development of NiO-Co3O4 nano-ceramic composite materials as novel photocatalysts to degrade organic contaminants present in water

2014
Novel ceramic oxides have been increasingly focused in recent years because of their potentialapplications in environmental purification especially to treat organic contaminants present in water. In thisresearch work, a set of NiO-Co3O4 nano-ceramic composite materials were prepared by a simple refluxcondensation method using nickel acetate / cobalt ...
