“…[13][14][15][16] In addition, the good match of thermal expansion coefficient and good physical and chemical compatibility between mullite (4.4-5.6 × 10 −6 / • C) and SiC (4.3-5.4 × 10 −6 / • C) are another advantage for the adoption of mullite as outer coating material. 17 However, the traditional technologies, such as chemical vapor deposition, 14,18 slurry dipping 19,20 and pack cementation 1,3 are either high-cost or time-consuming. Hydrothermal electrophoretic deposition has been demonstrated to be a facile method to prepare dense coatings with high efficiency and simple operation.…”

“…Suitable materials for these outer coatings are silicates of aluminum, yttrium and zirconium. It was already shown in previous works, that mullite exhibits favorable protection up to 1550 °C, but fails at higher temperatures due to existence of eutectics at higher silica content [3]. The yttrium silicate system with its high melting compounds Y 2 SiO 5 and Y 2 Si 2 O 7 is expected to ameliorate oxidation resistance above this limiting temperature.…”

. In the present work we used the sol-gel process to prepare Y2SiO5 precursor sols suitable for electrophoretic deposition (EPD). The sol synthesis was performed through the controlled hydrolysis of alkoxide solutions of tetraethoxysilane and yttriumoxoisopropoxide. During sol development emphasis was put on characterization of particles size and zeta potential of the formed aggregates. We succeeded in synthesizing a clear sol containing polymeric aggregates with acceptable particle charge. The electrophoretic deposition on glassy carbon or C/C-SiC slabs led to homogenous layers. At low sol concentrations micro cracks in the deposited layers were observed whereas higher concentrations led to thin and dense layers. During constant current EPD a constant voltage was recorded indicating that the deposited layer does not lead to an increase in resistivity in this kind of EPD system.

Electrophoretic deposition (EPD) method has been developed for the fabrication of manganese dioxide (MD) films for application in electrochemical supercapacitors (ES). Anionic dyes were used as dispersing agents for MD synthesis and EPD. The adsorption of pyrogallol red (PGR) and aurintricarboxylic acid (ACA) dyes on MD was attributed to catecholate and salicylate type of bonding respectively involving chelation of Mn atoms on the MD particle surface. The adsorption of the dyes on MD allowed efficient dispersion, charging and deposition. The higher charge/mass ratio of ACA, compared to that of PGR, allowed deposition at lower dye concentration and lower voltages. The kinetics and mechanism of deposition were discussed. Electrochemical testing results showed that the MD films prepared by the EPD method are promising for application in ES. The highest specific capacitance of 409 F g 21 was obtained at a scan rate of 2 mV s 21 .
