“…One of the classes is to make a solid solution consisting of BCZT-BFO, BZT-BFO, BT-BFO, BNT-BFO. Including BFO in the ceramic will enhance its magnetic properties as findings have been reported [21]. This will play an enhance role for the magnetic, dielectric, and ferroelectric properties of a material and it can be utilized to make capacitors, sensors, energy devices and manipulated in microelectromechanical systems (MEMS).…”

Multiferroics like [(Ba0.85Ca0.15) (Zr0.1Ti0.9) O3, BCZT] and (BiFeO3, BFO) with stochiometric amount were prepared mixed oxide solid state route adding CuO. The compositions were confirmed by X-ray diffraction technique, FTIR confirmed the formation of bonds and the clear idea of bonding pairs, FESEM supported the results of microstructure, and it was revealed that the addition of CuO increased the densification while it was also served as a sintering agent. The impedance spectroscopy (IS) was the tool that explain the relaxation phenomenon of the composition making agreements with the conduction mechanism that the material can be used as negative temperature coefficient of resistance (NTCR) for the applications of capacitors, sensors, actuators, and energy devices.

“…The FLA-assisted sintering of only a few ceramics, such as scandia-stabilized zirconia films [15], yttria-stabilized zirconia films [16], hafnia-zirconia thin films [17], and titanium dioxide samples [18], has been demonstrated. However, the photonic processing of alumina is challenging due to its low absorption in the visible range because of a wide bandgap of 7-8 eV.…”

Photonic Sintering of Oxide Ceramic Films: Effect of Colored FexOy Nanoparticle Pigments

Alumina and zirconia thin films modified with colored nano-FexOy pigments were sintered by the flash-lamp-annealing method. We selected a nano α-Al2O3 and micron α-Al2O3 bimodal mixture as the base precursor material, and we doped it with 5 vol% of FexOy red/brown/black/yellow pigments. The coatings were deposited from nanoparticle dispersions both on glass and on flexible metal foil. The characteristics of the thin films obtained with the use of various additives were compared, including the surface morphologies, optical properties, crystallinities, and structures. Flash lamp annealing was applied with the maximum total energy density of 130 J/cm2 and an overall annealing time of 7 s. Based on the simulated temperature profiles and electron-microscopy results, a maximum annealing temperature of 1850 °C was reached for the red Al2O3: Fe2O3 ceramic film. The results show that red α-Fe2O3 pigments allow for the achievement of maximum layer absorption, which is effective for flash lamp sintering. It was also possible to use the selected red α-Fe2O3 particles for the flash-lamp-assisted sintering of ZrO2 on a 30 µm-thin flexible stainless-steel substrate.

An inorganic, high temperature (∽600°C) thermochromic sensor is synthesized from a chemically bonded ceramic composite. The ceramic composite is composed of thermochromic 10 wt.% chromium‐doped alumina (Cr:Al2O3) powder blended with a low‐reacting temperature (around 250°C) phosphate binder, Al(H2PO4)3, (ADP). It has been reported that Cr‐doped alumina exhibits thermochromism at high temperatures, typically around 500‐600°C. Previously infrared (IR) irradiation has been used to successfully convert ADP to a ceramic aluminum phosphate (AlPO4) phase that can bind ceramic components together. Here, an ultra high‐power (tens of kilowatts per square centimeter) flash lamp annealing (FLA) system is evaluated as an alternative photonic heating process to rapidly transform ADP to this ceramic. While IR lamps require 30 min to fully transform the ADP binder, FLA processes require less than 1 min and provide more dense microstructures, opening opportunities to additively manufacture ceramic components without the need for a post‐processing heating step. Final ceramics exhibit reversible thermochromic behavior, transitioning from pink to dark gray as the temperature increases from 25°C to 600°C. Here, we demonstrate the ability to use this technology to fabricate a temperature warning system for heated objects that are not yet emitting significant visible black‐body radiation.This article is protected by copyright.
