A microporous ceramic capillary-action filter plate (22) made of recrystallized silicon carbide, i.e. pure silicon carbide. Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. Grains of silicon carbide can be bonded together at elevated temperatures to form very hard ceramics. Unlike other types of silicon carbide materials, which uses additives (binders) to help bond the silicon carbide particles together, re-crystallized silicon carbide ceramics are produced from pure silicon carbide powder having bimodal grain size distribution, e.g. extremely fine and coarse grains. A filter plate based on pure crystallized silicon carbide is extremely corrosion resistant material which enables significantly longer lifetime of the filter plate also in filtration application wherein fluorine is present. |
