Effect of the Addition of Potassium or Lithium on the Columbite Precursor Microstructure

open access: yesMaterials Research, 2002
Pechini method has been used to synthesize MN powders with stoichiometric control. By this method, K and Li-doped MN in the range from 0.1 to 5.0 mol% of dopants have been obtained at relatively lower temperatures than it is possible with the ...

Preperation of hydroxyapatie-alumina coated zirconia composites [PDF]

open access: yes, 2007
Hydroxyapatite (HAp) bioceramics as bone substitute materials have unique biocompatibility feature among phosphate groups. How ever, the low fracture strength and poor fatigue resistance due to the instability of OH- groups limit the use of HAp for load ...
