Incorporating graphene into a sintered ceramic tape: Structural and magnetic properties of a zirconia-graphene composite

Structural and magnetic behavior of zirconia‐magnetic particles and zirconia‐graphene composite ceramics

“…After the composite production, the viscosity must increase so that the composite's surface remains level before the solvent evaporate. 25,26,32 Thermogravimetric analysis (TGA) provided us information on the weight loss of the zirconia-magnetic particles and zirconia-graphene composites as the temperature increases. The thermograms obtained are presented in Figure 3.…”

Incorporating sugarcane bagasse ash into Al2O3 ceramic tapes

“…When subjected to shear stress, its molecules tend to orient themselves in the direction of the applied force. 32,33,25 Zhao et al 34 observed that the higher this force, the greater the ordering and, consequently, the lower the apparent viscosity. This behavior is typical of ceramic suspensions and considered suitable for obtaining ceramic tapes with good plasticity, homogeneous, and flat green surfaces.…”

“…We can see a decrease in viscosity with an increase in the shear rate, which characterizes a behavior for non‐Newtonian fluids independent of time and pseudoplastic. When subjected to shear stress, its molecules tend to orient themselves in the direction of the applied force 32,33,25 . Zhao et al 34 observed that the higher this force, the greater the ordering and, consequently, the lower the apparent viscosity.…”

“…Alumina with a high purity level of 99.9%, and grain size of about 150 nm (Taimei Chemicals), and 10.0 wt% SCBA waste were used as ceramic powder. The mixing of the powders occurred in a similar way to the work done by Alves et al 25 The suspension was prepared with 27.18 wt% distilled water, 1.0 wt% dispersant (polyelectrolyte, dolapix CA, Zschimmer & Schwarz), and 45.0 wt% ceramic powder in a ball‐milling process for 24 hours. Afterward, 25.3 wt% binder (polymethyl methacrylate, acrylic emulsion, Clariant), 0.76 wt% plasticizer (isopropyl alcohol, Vetec), 0.51 wt% surfactant (coconut diethanolamine, Stepan), and 0.25 wt% antifoaming agent (active silicone polymer, antifoam A, Sigma‐Aldrich) were added to the mixture, and it homogenized for 24 hours.…”

Temperature sensor based on micro‐nano fiber coated with ZnO composite graphene

“…On the one hand, the electron transport performance of the metal oxide material is improved; on the other hand, it has a certain preventive effect on preventing the agglomeration of metal oxide nanoparticles (Nps). A lot of efforts based on Gr composite have been made to enhance the sensor performance 18,19 . Zinc oxide (ZnO), as a group II–VI wide‐bandgap semiconductor material, exhibits a high exciton binding energy, electron mobility, and radiation hardness 20–22 .…”
