Natural tourmaline as an efficient alternative to ceramic-type material for plasma spraying

Preliminary Characterization of Corn Cob Ash as an Alternative Material for Ceramic Hollow Fiber Membrane (CHFM/CCA)

Currently, exchanging trends in the expensive usage of ceramic materials such as alumina, zirconia etc. into economical ceramic raw sources have been studied extensively over the last decade for various technological applications. Despite the fact that this ceramic compound or elements offer a great performance and stability, especially at high temperature and corrosive or acidic conditions, th...

ß-tricalcium Phosphate Granules as an Alternative Material for Ocular Implantation

Background: Some types of implants used for orbital implantation have side effects and complications. In this study we have evaluated beta-tricalcium phosphate (ß-TCP: ChronOS) granules as an orbital implant. Methods: Eighteen rabbits randomly allocated to four groups. Right eye enucleation performed in groups I to III followed by filling with autologous bone particles (n=5), a mixture of autol...

Air-plasma spraying colloidal solutions of nanosized ceramic powders

Coatings prepared from nanosized powders were obtained by spraying ethanol-based colloidal solutions into a plasma plume. The powders investigated included 40 nm γ -Al2O3, 75 nm 8 wt% Y2O3-ZrO2, and 750 nm 25 wt% CeO2-ZrO2. Spray distances from approximately 50 to 63 mm were required to achieve significant coating deposition. As observed in the TEM, the typical lamella morphology of air plasma ...
