Cerafiber: Spun refractory fibres, made from electricallymelted alumina and silica.
Cerachem Fiber: Spun refractory fibres, made fromelectrically melted alumina, silica and zirconia.
Cerachrome Fiber: Spun refractory fibres, made fromelectrically melted alumina, silica and chromia.
All three fibres are resistant to chemical attack, except forhydrofluoric and phosphoric acids and strong alkalies.
Bulk refractory fibres.
MAXIMUM CONTINUOUS USE TEMPERATURE
Cerachem Fiber: 1425°C
Cerachrome Fiber: 1425°C
The maximum continuous use temperature depends onthe application. In case of doubt, refer to your localThermal Ceramics distributor for advice.
- Excellent thermal stability: resist devitrification at high temperature
- Low thermal conductivity
- Excellent thermal shock resistance
- High chemical stability
- Contain no binders or corrosive agents
- Resilient up to high temperatures
- Low heat storage capacity
- Excellent sound absorber
- The packed density of bulk refractory fibres isbetween 90 and 200kg/m3 depending on the forceapplied to pack it. It is very difficult to obtain adensity higher than 200kg/m3 by hand packing.
