Advantages:
● Short fiber wet forming, three-dimensional isotropic structure
● Good electrical insulation, excellent performance in induction furnaces
● Good thermal insulation performance
● High purity, low impurity content
● Excellent seismic resistance and corrosion resistance
Application:
Primarily used in high-temperature environments under vacuum or inert gas protection, such as SiC induction furnaces/resistance furnaces, silicon single-crystal/polycrystalline furnaces, high-temperature sintering furnaces, optical fiber preform/ drawing towers, thermal high-temperature furnaces, etc., especially suitable for electromagnetic induction furnaces.
