Improved Performance of Ceramic Solar Absorber Particles Coated with Black Oxide Pigment Deposited by Resonant Acoustic Mixing and Reaction Sintering

Spark plasma sintering of ductile ceramic particles: study of LiF

Densification of cuboidal micrometer-sized lithium fluoride particles as ductile ceramic by spark plasma sintering (SPS) was investigated. Specimens were fabricated at different pressures and temperature conditions, ranging from 2 to 100 MPa at 500 C and from 200 to 700 C under 100 MPa of applied pressure, respectively. Dense specimens of 99 % relative density were fabricated by heating to 500 ...

The Black Hole: Scatterer, Absorber and Emitter of Particles

Accurate and powerful computational methods developped by the author, based on the analytic resolution of the wave equation in the black hole background, allow to obtain the highly non trivial total absorption spectrum of the Black Hole. As well as phase shifts and cross sections (elastic and inelastic) for a wide range of energy and angular momentum, the angular distribution of absorbed and sc...

Fabrication of a yellow ceramic nano pigment based on zirconium oxide (ZrO2) and iron oxide as dopant (Fe2O3)

In this study, yellow ceramic nano pigments based on ZrO2 (zirconium oxide) were synthesized by solid state method using different value of Fe2O3 as dopant. The pigments were dispersed in solvent by a planetary ball mill and then the inks were printed on the ceramic surface using screen printing method. The samples were analyzed using scanning electron microscopy (SEM), X-ray diffraction spectr...

Study the Color properties of CoAl2O4 as a Blue Ceramic Nano Pigment fabricated by Co-precipitation and Printed on Ceramic

CoAl2O4 nano pigments were fabricated using cobalt chloride and aluminum oxide as a ceramic blue pigment by co-precipitation . The product was calcinated at 1200°C. Three samples were made under different conditions and homogenized in a solvent using a milling system to prepare an ink. It has been printed on a ceramic by silk screen method. The powder was characterized by XRD, SEM and colorimet...
