- Ceramic foams have
an interesting combination of properties, such as low weight, high
temperature stability. high permeability, high porosity, low thermal
conductivity and low heat capacity. These properties have lead to a
diverse field of applications, ranging from metal melt filtration,
ion-exchange filtration, heat exchangers, catalyst support, refractory
linings, thermal protection systems, diesel soot traps, flame rectifiers
and solar radiation collectors. Recently the bio-technology and
biomedical industries are employing ceramic foams made of
hydroxyapatite, which can simulate bone and bio-implants.
- Engineered foams
have cellular structures which are categorized as either open call or
closed cell foams. Foams consists of an assembly of irregularly shaped
prismatic or polyhedral cells connected to each other with solid edges
or faces. Engineered foams have been manufacturers from polymers,
metals, glasses and ceramics. Ceramic foams are porous brittle materials
with closed, fully open or partially interconnected porosity. Porous
ceramic materials are being used in many industries and continue to be
very active area of research for yet uncharted applications.
- Open cell ceramic
foams are used for a very wide range of applications. The excellent
thermal shock resistance facilities their use for metal melt filtration
and diesel engine exhaust filters. Ceramic foam filters improve molten
metal casting quality by removing non metallic inclusions.
- Open cell ceramic
foam manufacturing techniques can be classified into three general
categories: Sponge-replication, foaming agents or space holder method.
The Sponge replication was first developed in the early 1960s.
- The second technique
is based on gas bubbles in preceramic melts. Gas evolving constituents
are added to the melt. During the treatment bubbles are generated,
causing the material to foam . This process was introduced in 1973 by
sunderman.
- The manufacturing
process for Hi‑Por relies on the gelation of an organic binder to
stabilise the foamed structure. It should not be confused with
reticulated foam, which is produced from a polyurethane skeleton. The
essential components of the process are ceramic powder, organic binders,
dispersing agents, a foaming agent and water.
- Ceramic foams have
so far been produced in a variety of materials with various cell sizes,
densities and degree of interconnectivity. Foams are usually produced
with densities between 10 and 40% of theoretical and pore sizes between
100 µm and 1 mm.
