Each type of ceramic fiber board is made up from corresponding blowing fiber, common (COM), standard (STD), high alumina (HA), high purity (HP) or zirconia (HZ). They are produced by vacuum forming technology. |
|
The ceramic fiber boards have hard texture, excellent toughness and intensity, and excellent erosion resistance. |
|
Working Temperature depends on working conditions, heating method and environment atmosphere, etc. |
