TL;DR: A chemical, physical, structural and morphological characterization of the EAFD is carried out by using granulometry analysis, chemical analysis, scanning electron microscopy (SEM), energy dispersive spectroscopy via SEM, X-ray diffraction (XRD) and MössbauerSpectroscopy.

TL;DR: In this paper, the physical, chemical, thermal, mineralogical, and morphological characteristics of three types of RHA, produced according to three distinct methods (grate furnace, fluidized bed, and suspension/entrained combustion).

TL;DR: The findings point to the existence of an environmentally suitable use for all wastes from the rice production cycle, which shows potential to be used as a by-product in many different applications, but not yet consolidated.

TL;DR: In this article, a literature review was conducted, and then selected techniques were used to produce silica, which was characterized by XRF, XRD, particle sizing, specific weight, specific surface area, total carbon, and SEM.

TL;DR: In this paper, the authors used optical and scanning electron microscopy, microhardness test, glow discharge optical emission spectroscopy (GDOES) and X-ray diffraction (XRD) to characterize the nitrided layer.
