Ceramic fiber boards are made up of ceramic fiber cotton to join a small amount of organic or inorganic binder, the surface smooth, precise dimension, good toughness, and can be arbitrary cutting. It has excellent thermal stability, can be widely used in metallurgy, ceramics, glass, petrochemical, non-ferrous metals and other industrial kiln. It is the ideal heat preservation, thermal insulation material.
