The influence of mechanical activation on structural evolution of nanocrystalline SrTiO3 powders
(Elsevier, 2017)
Structural changes caused by mechanical activation of SrTiO3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 ...
Geometrical and electrical properties of NTC polycrystalline thermistors vs. Changes of sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2006)
NTC thermistor powder was made of a Mn, Ni, Fe and Co oxide mixture calcinated at 1050°C / 60 min. The powder was milled in a ball mill down to an average particle diameter of 0.9 μm. Small disc shaped pills of the powder ...
Mechanical activation and HIP of ZrB2-TIB2 based composites for hypersonic system
(Krakow : Agencja Reklamowa EURO GRAPHICKrakow : Polskie Towarzystwo Ceramiczne, 2022)
Ultra-high temperature ceramics, such as ZrB2, are convenient for application in hypersonic systems due to melting point higher than 3000 °C and excellent ablation resistance. For such application further improvement by ...
