- Gelcasting is a
forming process similar to slip casting for making complex-shaped parts.
In gelcasting, a slip of ceramic powders in a solution of organic
monomers, is poured into a mold and is polymerized forming a strong,
crosslinked solvent-polymer gel filled with the ceramic powder.
- Gelcasting is a
highly versatile fabrication process. It has been used to make parts
ranging in size from <1 g to >6 kg. Complex shapes with thin sections as
small as 0.2 mm have been gelcast. Conversely, large rods up to 4 inches
in diameter have been made.
- Gelcasting has been
demonstrated in most of the major ceramic systems such as alumina,
aluminum nitride, boron carbide, ferrites, silicon, silicon carbide,
silicon nitride, zinc oxide, and zirconia as well as some of the more
obscure ones such as cerium oxide, europium oxide, hydroxylapatite, and
tin-doped indium oxide.
- Highly porous
Gel-casting ceramics are used in medical applications.
- Transparent
submicrometer grains alumina are formed by gel casting using agar as
gelling.
- Porous Gelcast
ceramics for Bone Repair Implants.
- Direct Gel-Casting of
Zirconia for Dental Application.
- Gelcasting has also
been successfully used inmaking highly porous ceramics by direct foaming
tech-niques .
- Powder Injection
Moulding (PIM) is a well-established forming technique for ceramics,
particularly suited to the production of complex shapes.
