In this paper, porous SiC ceramics (PSCs) were fabricated from photovoltaic waste at low temperatures. The effects of different additives and sintering temperatures on PSCs were studied in detail. The temperature of PSCs preparation can be reduced to 850 °C by adding MoO 3 as catalyst. The PSCs are reinforced by mullite rods …
Learn MorePorous SiC ceramic (PSC) is a kind of structural and functional ceramic material with high specific surface area, high porosity, and good corrosion resistance [13]. Due to the strong covalent bonding of Si C and the small diffusion coefficient of SiC, the sintering temperature of pure PSCs is usually higher than 1900 °C [ [14], [15], [16] ].
