Fiber blankets are high-temperature insulation materials composed of interwoven alumina, silica, and zirconia fibers. They are commonly used in various industrial applications for their thermal stability, low weight, and resistance to thermal shock.
Here’s a breakdown of ceramic blanket specifications:
Key Properties:
Composition:
Primarily made of alumina (Al₂O₃), silica (SiO₂), and sometimes zirconia (ZrO₂).
Temperature Rating:
Typically rated for continuous use up to 1260°C (2300°F) and higher, with some grades reaching 1430°C (2606°F) or even 1650°C (3000°F).
Density:
Available in various densities, typically ranging from 64 kg/m³ to 160 kg/m³, with the lowest density potentially reaching 64 kg/m³.
Thickness:
Offered in various thicknesses, commonly 12.5mm, 25mm, and 50mm.
Dimensions:
Supplied in rolls with varying widths and lengths, often 600mm or 610mm wide and 3600mm to 7200mm or more in length.
Thermal Conductivity:
Varies with temperature, generally decreasing as temperature increases. For example, at 400°C, thermal conductivity might be 0.090 W/m·K, and at 1000°C, it might be 0.180 W/m·K according to Scribd.
