Microstructure and mechanical behavior of

2020922 Tapes of TiO 2MnOdoped alumina dAl 2 O 3 and pure alumina Al 2 O 3 were shaped via tape castingLaminates with three different layer nuers and respective thicknesses were produced and sintered at 1200°C The microstructure and mechanical behavior of laminates were investigated and compared to the respective monolithic references dAl 2 O 3 and Al 2

Preparation and Characterization of Alumina Nanoparticles

Al 2 O 3 nanoparticles were synthesized using laser ablation of an aluminum Al target in deionized water NdYAG laser emitted the light at a wavelength of 1064 nm was used as a light source The laser ablation was carried out at different energies of 1 3 and 5 J The structure of ablated Al particles suspended in deionized water was investigated using Xray diffraction XRD

Jetting from cavitation bubbles due to multiple

2018118 For each bubble the collapse time T C ie the measured time between the instants when the bubble reaches its maximum and minimum sizes is significantly different from the natural collapse time in the absence of pressure waves predicted by the Rayleigh model T R = 0915 R m a x ρ / p ∞ − p v 1 / 2 where ρ is the water density p ∞

Porous alumina ceramics by gel casting Effect of type of

2019614 Flowable and stable porous alumina ceramics suspensions containing 36 vol alumina and 25 vol of expandable polymer spheres or glassy carbon as sacial template were gelcast to produce green bodies following our previous work 15 The gelcast bodies were unmolded and kept at 25°C at a relative humidity of 25 for 85 hours

Introduction to Fluidization AIChE

20141121 gas leaks into and out of the bubbles Thus a more accurate version of Eq 5 is where u is the minimum bubbling velocity for the onset of bubbles in the bed and Y is the fraction of the gas in the bubbles which ranges from 0 to 1 As the gas velocity through the bed continues to increase the type of fluidization changes as shown in

Investigation of meltgrowth alumina/aluminum titanate

202153 Naturally large bubbles formed by diffusion or coalescence are more likely to escape from the molten pool in time In contrast some small bubbles whose movement velocity is lower than the solidifiion rate of molten pool or even fail to move due to the viscosity resistance are entrapped in the melt and form gas cavities as shown in figure 4
