The mechanically induced structural disorder in barium hexaferrite, BaFe12O19, and its impact on magnetism.
The response of the structure of the M-type barium hexaferrite (BaFe12O19) to mechanical action through high-energy milling and its impact on the magnetic behaviour of the ferrite are investigated. Due to the ability of the (57)Fe Mössbauer spectroscopic technique to probe the environment of the Fe nuclei, a valuable insight on a local atomic scale into the mechanically induced changes in the h...
متن کاملMagnetic and Structural Properties of Barium Hexaferrite BaFe12O19 from Various Growth Techniques
Barium hexaferrite powder samples with grains in the μm-range were obtained from solid-state sintering, and crystals with sizes up to 5 mm grown from PbO, Na₂CO₃, and BaB₂O₄ fluxes, respectively. Carbonate and borate fluxes provide the largest and structurally best crystals at significantly lower growth temperatures of 1533 K compared to flux-free synthesis (1623 K). The maximum synthesis tempe...
متن کاملPlatinum-Based High Temperature Selective Absorber Coatings
In photothermal energy conversion the absorbed solar flux is converted to heat which is then used directly or is converted to mechanical or electrical energy. Efficient receiver design requires that thermal losses from the absorber surface, which is the hottest element of the system, be minimised. Receivers are, in fact, generally classified according to their operating temperature ( I , 2). Th...
متن کاملEnhanced wavelength-selective absorber for thermal detectors based on metamaterials
The dissipative electromagnetic energy absorption of tailored metamaterials can be exploited to improve the spectral sensitivity and selectivity of thermal detectors. The desired detector characteristics are engineered by tuning the singleor multiband absorption by resonance frequency, magnitude, and spectral bandwidth, strongly depending on the geometrical design of metamaterials. Here, the op...
متن کاملSelective Solar Absorber Materials: Nanostructured Surfaces
Current solar to thermal energy conversion technologies, including concentrated solar power (CSP) and solar water heaters (SWH) utilize absorber surfaces that collect incident solar radiation. However, these absorber surfaces emit thermal energy (at their temperature) in the infrared (IR) spectrum, resulting in decreased overall efficiency for solar-to-thermal conversion. Selective absorber sur...
