“…Ran et al (4) demonstrated that the addition of 2 wt% sepiolite improves the mechanical response in bone china bodies sintered from 1150 to 1250˚C. A similar outcome was previously obtained by Li et al (5) when sepiolite was added to the dough intended to be fired into sanitary bodies. Likewise, it has been possible to sinter cordierite-based ceramics, whose industrial application is widespread in several sectors, from sepiolite at temperatures in the range 1200-1300˚C (6,7).…”

Sintering of sepiolite-rich by-products for the manufacture of lightweight aggregates: technological properties, thermal behavior and mineralogical changes

A sepiolite mining by-product (SEP) has been studied as major component for lightweight aggregate (LWA) manufacture. Pellet bursting during firing was avoided by the addition of 2.5 wt% of thermoplastic waste (P) and 2.5 wt% P + 2.5 wt% carbon fiber residue (FC) in powder form. The mixtures were pelletized and then sintered at 1225º˚C for 4 minutes in a rotary kiln. Highly porous white LWAs with good mechanical strength were produced. A mineralogical study revealed the formation of amorphous phase ( > 50%) and minor proportions of enstatite, protoenstatite and diopside. Quartz was the only inherited mineral, appearing in the form of isolated phenocrysts within a general porphyritic texture. The result of this study suggests the promising use of sepiolite (whether or not in residue form) for the manufacture of high quality LWAs.

In this study, poly vinyl chloride (PVC)/ sepiolite composites were produced using an extruder. Two different sepiolite powders: white and gray were added to the PVC in order; 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.%. The morphology alteration, chemical behavior and mechanical properties of the powders and the composites were examined by X-ray fluorescence (XRF), tensile test, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and ultimate tensile strength (UTS). The results showed that the sepiolite white powder had 20.72 wt.% CaO and approximately half of the 20.81 wt.% SiO2 as compared to the sepiolite gray powder. The XRD analysis confirmed that the structure of calcined white sepiolite contained dolomite, while gray calcined-sepiolite contained zeolite. The composites with 5 wt.% sepiolite white or gray powders exhibited higher tensile strength. Increasing the quantity of both sepiolite powders in the composites deteriorated the surface with cracks and shifted the thermal degradation of the sepiolite gray toward higher temperatures.
