Thermal insulation vacuum formed ceramic fiber block
Thermal insulation vacuum formed ceramic fiber block
Ceramic Fiber Special Shape products are made of high purity Alumina fibrous and Alumina powde,
to be formed and fired in special equipment with advanced patent process, can withstand temperature
up to 1800 Celsius.
According to different temperature grades, refractory fiber product may add proper organic and inorganic
additives into polycrystalline mullite fiber, high alumina fiber, zirconic fiber, and aluminum silicate fiber etc. by
use of vacuum moulding methods, to manufacture all kinds of products with different temperature grades:
1000 degree, 1260 degree, 1400 degree, 1500 degree, 1600 degree, 1700 degree and 1800 degree. Its
varieties include two classes: fiber plate and fiber special-shaped product.
