Alumina



Alumina

• A high purity alumina mix, it has good

resistance to both acidic and basic slags.• It is the workhorse for a wide range of

alloys and melting applications; commonly

used for air melting furnaces but can also

be used in a vacuum melting application.

• Maximum service temperature 1800°.



Chrome Alumina• The small addition of chrome in the

alumina improves the resistance to slagattack and greatly improves the longevity

of refractory life.

• Ideal for air melting applications, but notrecommended for vacuum melting

applications.

• Maximum service temperature 1800°C.

Magnesia Stabilised Zirconia



Magnesia Stabilised Zirconia

• Stabilised with magnesia to prevent volumechanges, it has an excellent resistance to acidic

slags.• It is unaffected by Ni, Mo, Al, Fe, Pb and has

good resistance to Zr and Be.

• Widely used in vacuum melting applications for the melting of superalloys, this material exhibitssuperior resistance to thermal shock anderosion.

• It has low thermal expansionproperties. Maximum service temperature1900°C.



Lime Stabilised Zirconia• Stabilised with lime to prevent volume changes,

ideal for high temperature applications and for

use with platinum group metals.• Our lime stabilised zirconia products are

specially designed to counteract the glassy or siliceous slags produced when melting platinumalloys.

• It has excellent thermal shock properties anddisplays a superior resistance to spalling and

erosion.• Maximum service temperature 2000°C.



Magnesia• Has very good resistance to basic slags

and is widely used in vacuum meltingapplications for the melting of superalloys.

• It is non-wetted by Ni, Co and Fe based

alloys.

• Less dense than zirconia and preferred by

some customers for X-ray analysis.• Maximum service temperature 1700°C.

Mullite



Mullite

• This material has excellent thermal shock

properties; it has good abrasion and wear resistance with most alloys.

• It is not recommended for acidic slags and

elevated temperatures.• An ideal material for furnace bricks,

element carriers and parts demanding

good hot loading durability.• Maximum service temperature 1700°C.

Zircon



Zircon

• Contains high strength and good

resistance to thermal shock properties dueto a dense structure and increased silica

content, good resistance to acidic slags

and is commonly used for non-ferous andprecious metal melting applications.




Silicon Carbide• An extremely dense material with superb

thermal shock properties.• Highly resistant to metal penetration and

non-wetted by non-ferrous alloys.

• The workhorse for non-ferrous metals in

air melting applications.




Fused Silica• A light material providing excellent thermal

shock properties and extreme volumestability at elevated temperatures.

• Commonly used for 'one shot liners' with

superalloys in a vacuum furnaceapplication.

• Maximum service temperature 1650°C

CERABLANKETS/CERACHEM



CERABLANKETS/CERACHEM

BLANKETS Furnace, Kiln, Fired Heaters,

Hydrogen Reformer linings.

Also insulation of Steam andGas Turbines, investment

casting moulds, reusable

insulation for field stress

relieving, fire protection and

acoustic insulation at hightemperatures.





VENEERING MODULES Hot face veneering for existing

Furnaces , Kilns and Heaters

where the lining is in a

reasonably good condition anddoes not require immediate

replacement .

Veneering offers reduction inheat loss, leading to fuel

savings.

Further, the life of refractorylining is extended due to

protection offered by ceramic

fibre.
