Our
principal materials are:
Alumina
Aluminium oxide (Al2O3) provides the basis for one of the most important technical oxide ceramic material groups. Alumina materials have established themselves as the material of choice for a wide range of applications. Densely sintered alumina is characterised by
- high strength and hardness,
- temperature stability,
- Electrical insulation,
- high wear resistance and corrosion resistance even at high temperatures.
A range of high purity alumina materials for use in high temperature,
wear, corrosive or electrical insulation applications. Stock available
in rods, tubes,
thermocouple protection tubes,
plates, crucibles, insulators.
Special shapes also available on request.
Mullite
Synthetic Mullite (Al2O3–SiO2) products are available in both impervious and porous forms. Densely sintered (impervious) mullite combines high strength with good thermal shock resistance. Porous mullite have a reasonably high strength combined with low thermal expansion giving improved levels of thermal shock.
Mullite ceramics with high thermal shock and operating temperatures up to 2910F (1600C) are used in furnaces, heaters, electrical insulation, wear and corrosion resistant applications. Stock available in rods, Mullite tubes, insulators, thermocouple sheaths, crucibles. Special shapes also available on request.
Silicon
Carbide
Porous silicon carbides with excellent thermal shock, high strength
and high temperature operating capability up to 2910 F (1600C).
Excellent for use in furnaces and molten metal applications due
to it’s non wetting properties. Stock available in tubes,
thermocouple sheaths, rods, crucibles and beams.
Zirconia
A range of zirconia materials either dense or with porosity. These
materials offer high temperature capability upto 4370F (2400C)
as well as excellent performance in areas of high wear and corrosion.
Products are available as tubes, rods, Zirconia crucibles and
a wide range of other shapes.
Rare
Earth materials
Rare earth refractory oxide ceramics exhibiting very high thermal
stability, wear resistance and strength. Widely used in applications
above 3090F (1700C), nuclear, high performance metal melting,
oxygen sensors and semiconductor applications. Products are offered
in a wide range of shapes including crucibles, ceramic tubes,
laboratory furniture and thermocouple sheaths.
Refractory
Materials
In addition to the principle materials listed above Anderman also
offers a range of specialty refractory materials for high temperature
applications.
-
Cordierite
-
Alumina Titanate
-
Fused Silica
Technical
Ceramics
In addition to the principal materials listed above we are also
able to offer a number of special technical ceramic materials
for a range of high temperature, wear and electrical resistance
applications.
Our
range of ceramic materials is considerable and our experience
enables us to source other, more specialist materials, upon request.
We can manufacture to most dimensional requests and also hold
considerable stocks of standard shapes and sizes.
With our manufacturing partners we have over 100 years experience
in ceramic forming technology utilising processes such as extrusion,
slip casting, injection moulding, isostatic pressing and uniaxial
pressing.
