One of the main topics of the actual research in the field of cemented carbides concerns the
development of new composites, with partial or total substitution of the traditional cobalt …

Undoped and Mn-doped ZnO samples were sintered at 1373, 1473, and 1573 K, for 2 h, in
air, and then quenched to room temperature. Defect concentrations in these samples at the …

The increasing number of normalized materials, promoters and users led to a significant
amount and diversity of databases and software for material selection, presenting differentiating …

Samples of Al-doped and Mn-doped ZnO with a doping level up to 1.2 mol% were sintered
at temperatures from 1100 to 1400C in air. dc Electrical conductivities of these samples at …

In PZT ceramics it is commonly observed that the tetragonal and the rhombohedral phases
may coexist around the morphotropic phase boundary (MPB). Some controversy still exists …

Cobalt is the standard binder in tungsten carbide (WC) hardmetals due to its compatibility
with the WC phase, resulting in composites with exceptional hardness and wear resistance. …

Grain growth in ZnO doped with 0.1 to 1.2 mol% Mn was investigated during isothermal sintering
from 1100 to 1300C in air. Mn doping promotes the grain growth of ZnO during sintering…

Polycrystalline ZnO doped with MnO, from 0.1 to 0.6 mol%, was prepared by conventional
ceramic processing. The effect of Mn doping on the electrical properties of ZnO was …

Hydroxyapatite powders with reproducibly different Ca/P ratios and powders with varying
amounts of co-precipitated magnesium, sodium and potassium were synthesized by a wet …

The densification and grain growth of ZnO doped with Al from 0.08 to 1.2 mol% were
investigated during isothermal sintering between 1100 and 1400 C. The Al dopant significantly …
