Thermal Ceramics Cerachrome Bulk Fiber
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Cerachrome is a bulk refractory fiber produced from an alumina-silica-chromia composition which provides for a maximum use limit of 2600°F (1427°C).

Engineered Fibers - Kaowool Engineered fibers are based on our extensive family of bulks. Value adding technology has been developed to allow Thermal Ceramics to tailor products to meet specific customer requirements. Fiber length, diameter, and surface treatment can be engineered as can the fiber content. Thermal Ceramics can work with you to produce a Kaowool Engineered Fiber to meet unique requirements. The various grades of fibers can be engineered for applications in plastic reinforcement, metal matrix composites, and automotive applications. Kaowool Bulk Fiber can be used as high-temperature loose fill or packing material in a variety of applications including expansion joint construction, furnace walls and base seals, low mass kiln car top construction, tube seal fabrication, and packing around hard refractory furnace components such as burner blocks.

These products are also used in secondary processes such as felting, vacuum forming boards and shapes, and the manufacture of specialty papers, textiles, high-temperature adhesives and moldable products.

Thermal Ceramics bulk fibers offer a maximum temperature range of between 2300° and 3000°F (1260° to 1549°C). They also provide excellent chemical stability and resistance to chemical attack. Exceptions include hydrofluoric acid, phosphoric acids, and strong alkalis. If wet by oil or water, thermal and physical properties will be fully restored after drying.

Compared to other refractory materials, bulk fibers and products made from them are lightweight, resistant to thermal shock, and provide a low thermal conductivity. The sound absorption capabilities of Thermal Ceramics bulk fibers are far superior than those of dense refractories or other insulating refractories.
