Metal–ceramic composite beads containing different amounts of tantalum and alumina, particularly 100 vol% 60–40 tantalum/alumina, are produced by the alginate gelation process. Sodium is used as gelling agent in metal–ceramic suspension, while a calcium chloride solution prepared to trigger consolidation As previous study, nozzles order obtain three sizes. The largest result be hollow, hence re...

Bone apatite contains carbonate and is therefore not pure hydroxyapatite. We have successfully developed sintered carbonate apatite (CA) with a concentration of carbonate of 6 weight% and have evaluated its osteoconductive and bioresorption characteristics. Cylindrical porous sintered CA and sintered hydroxyapatite (HA) measuring 4 x 4 mm with a porosity of 20% were implanted into surgically-cr...

Ultrafiltration membranes offer a progressive and efficient means to filter out various process fluids. The prime factor influencing ultrafiltration great extent is the porosity of employed. Regarding membrane development, alumina are extensively studied due their uniform mechanical strength. present research work specifically aimed towards investigation nanoporous membranes, as function sinter...

The article presents the study of alumina nanoparticles’ (nanofibers) concentration effect on strength properties pure nickel. samples were obtained by spark plasma sintering previously mechanically activated metal powders. dependence grain size and relative density compacts number nanofibers was investigated. It found that with an increase in nanofibers, average matrix particles decreased. eff...
