What are the different materials used in ceramic fiber products?

Ceramic fiber products are made from a variety of inorganic materials that can withstand high temperatures. The primary materials include alumina-silica (Al2O3-SiO2) fibers, mullite (3Al2O3路2SiO2) fibers, and alumino-borosilicate fibers. These materials are chosen for their high melting points, thermal stability, and resistance to thermal shock. Additionally, ceramic fiber products may incorporate other materials such as zirconium dioxide (ZrO2), calcium zirconate (CaZrO3), and hafnium oxide (HfO2) to enhance specific properties like strength, creep resistance, and chemical stability. The choice of material depends on the intended application and the temperature range the product needs to endure.
