Effect of beta-Si3N4 seeds on densification and fracture toughness of silicon nitride
(Ceramics International, 2006)
Composite materials based on Si3N4 were synthesized by introducing previously prepared beta-Si3N4 seeds into a mixture of alpha-Si3N4 and 10 wt% of sintering additive. The densification process during pressureless sintering ...
Effects of manufacturing conditions and heating on properties of electrochemically produced magnetite nano-powders
(Ceramics International, 2014)
Electrochemical (EC) synthesis of magnetite (Fe3O4) nano-powders of specific characteristics is investigated in the range of current densities of J=200-1000 mA/dm(2), and temperatures of T=295-361 K. The obtained powders ...
