“…Sepiolite is a type of fibrous silicate clay mineral rich of magnesium with a unit cell formula of Si 12 O 30 Mg 8 (OH) 4 (H 2 O) 4 ·8H 2 O and fine microporous channels of dimensions of 0.37 nm × 1.06 nm running parallel to the direction of fibers 18 19 20 21 . Benefitting from its large reservation, low cost, high efficiency and reusable attribute, sepiolite has been intensively studied in recent years 22 23 24 25 26 27 28 . Although the defibering treatment of sepiolite is a simple and cheap way to obtain mineral nanofibers for practical use, it has been less investigated except for a few exploratory researches which mostly involve destruction of its fibrous micro-morphology by ball milling and the use of expensive and sensitive agents 29 30 .…”

In this work, a new organic-inorganic composite filter was prepared. The thickness, pore size, air permeability, bursting strength and microstructure were characterized systematically, proving that coatings had regulatory effect on filters physical properties. Benefitting from the distinct coatings containing 5% sepiolite nanofibers after five times dilution, the physical properties of corresponding air filter exhibits the most favorable performance and meet the standard of air filter. When used as fuel filter, it satisfies the fuel filter standard and achieves the best performance after six times dilution. The contrast test on engine emission was taken based on auto filters coated with/without as prepared nanofibers. An obvious decrease in the emission of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxide (NOx) can be observed after installation of composite filter on vehicles. Under the high idle condition, gasoline engine emission decreased by 8.13%, 11.35% and 44.91% for CO, HC and NOx, respectively. When tested in the low idle condition, engine emission reduced by 0.43%, 1.14% and 85.67% for CO, HC and NOx, respectively. The diesel engine emissions of CO, NOx and total amount of HC and NOx decreased by 32.26%, 3.28% and 4.66%, respectively. The results illustrate the composite installation exhibits satisfactory emission reduction effect.

“…The second trend was that Tg points were not visible when the heating rate was 2 o C/min, in contrast, the broad crystallization peak at around 650 o C became weak when the heating rate is 10 o C/min. These two trends suggest that the crystallization of the glass frit was influenced by the glass transition and softening [15]. To compare the glass transition points and the crystallization temperatures, the characteristics data derived from the curves which were obtained with the heating rate of 5 o C/min were selected [16].…”

The influence of temperature on the crystallization and the melting of the glassy frit was discussed. SiO 2 -B 2 O 3 -Al 2 O 3 -TiO 2 frits were obtained by melting batches at different temperatures, were investigated by DTA and the crystallization energy was calculated. The fluidity of the frits upon heating was estimated based on the sintering images. XRD measurements were applied to identify the crystalline phase of the sintered frits. The results show that the frit has reduced activation energy when the melting temperature is high. However, the melting temperature does not have effects on the transition and crystallization temperatures of the glass frit. Although the frit could crystallize at a low temperature, a much higher temperature has to be used for the sintering of the frit to obtain enamel glaze with a high flatness.

“…Higher refractive index (1.92-1.97), wear-impact resistance, thermal shock and the chemical durability of zircon impart excellent properties to the surface of sanitaryware glaze [12,13]. Owing to the high cost of zircon, several studies have been conducted aiming to reduce its usage or completely replace it by more economical alternatives.…”

Zircon (zirconium silicate; ZrSiO 4 ) is an essential compound of sanitaryware glaze due to contributions to the final properties of the surface. In this study, the effect of zircon particle size on the surface properties (microstructural development, opacity, roughness, hardness and bacterial activity) were studied. Initially, zircon powder was milled by planetary mill at different times (0-25 min) and added to an industrial sanitaryware glaze recipe. Four different glaze suspensions were prepared, applied to a sanitary ware body and sintered in an industrial tunnel kiln at 1220°C for 16 h. The effect of milling is clearly observed via SEM investigations by uniform distribution of zircon grains with a size reduction to 0.38 μm. This uniform distribution and reduction in particle size provides improvements in opacity (L * value measured as 91.47) and hardness (Hv was 6.3 (±0.3) GPa) values. According to AFM studies, the average roughness decreased to 10.94 nm when a 25 min milling process was used. The antibacterial activities of two samples (milled for 0 and 25 min) were analyzed against Escherichia coli and Staphylococcus aureus. Although both samples did not show any antibacterial activity, the number of viable bacteria on the samples milled for 25 min decreased drastically compared to the one not milled. A smoother glaze surface facilitated less sites for adherence and accommodation of bacteria and hence a decrease in bacterial colonization was obtained.
