Traditional ceramic fibers are made from inorganic materials, primarily aluminium oxide (Al2O3) and silicon dioxide (SiO2),with very high thermostability. Under normal circumstances standard ceramic fiber can be applied at temperatures up to 1260 °C. By adding small amounts of, e.g., zirconium oxide (ZrO2) the application temperature can be increased to approx. 1600 °C.

Aluminum Melting and holding Furnace Lining construction and baking recommendations1. Mixing: The castable material should be stirred by a forced mixer with a rotation speed of not less than 26 revolutions per minute, dry mixing for 2-3 minutes, then add clean water. The water dosage should be added
