Low temperature sintering additives for silicon nitride

open access: yes, 2003
Pressureless sintering of Si3N4 with two new additives based on the Li2O-Y2O3 system (LiYO2) and on the Li2O-Al2O3-SiO2 system (LiAlSiO4) were investigated in this study. Experiments were conducted in the areas of powder processing, sintering optimization, phase transformation characterization and microstructural development.

Sintering of Alumina-Reinforced Ceramics Using Low-Temperature Sintering Additive

open access: yesCrystals
Reinforced alumina ceramics are renowned for their high hardness and strength among common oxide ceramics. However, high-temperature or high-pressure treatment is necessary for maximizing values of strength and hardness. In this paper, liquid-phase-assisted pressureless sintering of alumina reinforced with zirconia was studied.

The effect of core-shell engineering on the energy product of magnetic nanometals. [PDF]

open access: yes, 2018
Solution-based growth of magnetic FePt-FeCo (core-shell) nanoparticles with a controllable shell thickness has been demonstrated. The transition from spin canting to exchange coupling of FePt-FeCo core-shell nanostructures leads to a 28% increase in the ...

New sintering process adjusts magnetic value of ferrite cores [PDF]

open access: yes, 1964
A two-phase sintering technique based on time and temperature permits reversible control of the coercive threshold of sintered ferrite cores. Threshold coercivity may be controlled over a substantial range of values by selective control of the cooling ...

Effect of sintering temperature and heat treatment on electrical properties of indium oxide based ceramics [PDF]

open access: yes, 2008
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.
