Ceramics > CERAFLEX
CERAFLEX is a yttria stabilized, ultra thin, tough, flexible zirconia ceramic material in thin sheet form. CERAFLEX is manufactured under carefully controlled conditions using special Doktor blade technology. With this technology sheets as thin as 0.05 mm thick and as large as 200 x 200 mm square can be manufactured. (Larger sizes require thicker material) Standard thickness are 0.100, 0.200 & 0.500 mm thick (.004", .008" & .020").
CERAFLEX is available as either partially or fully stabilized material. For electronic substrates and other mechanical uses requiring high strength and fracture toughness, partially stabilized material containing 3 mole % yttria is recommeded. For use in solid oxide fuel cells, oxygen sensors, and applicaions requiring high oxygen ion conductivity, fully stabilized 8 mole % yttria is used. Both materials are available with fine via holes, grooves and as polished substrates.
...Highly elastic and flexible ceramic made by forming zirconia
into sheets of 0.05 to 1.0 mm in thickness, and having heat, corrosion,
and abrasion resistance
Zirconia sheets stabilized with scandium. Although more expensive, CERAFLEX:SC has been found to have 3 times the ionic conductivity of yttria stabilized material. This can lower the operating temperature by 200oC without reducing the ionic conductivity performance.
ZIRCONIA GREEN SHEETS (ZGS)
For those who fabricate SOFCs by co-firing zirconia and electrode material together, we have pre-formed thin sheets of "green" zirconia. ZIRCONIA GREEN SHEETS can save money and time. These are unfired thin sheets of zirconia fully stabilized with yttria and are ready for your normal processing. Post firing sizes up to 100 x 100 mm or 200 mm diameter and thicknesses from 0.15 mm to 0.63 mm are available. Fired ZGS are gas tight, have a density of 5.85 g/cm3 and bending strength of > 256 Mpa.
