Ceramic Fiber Board and Vacuum Shaped Products are made of high purity Alumina fibrous and Alumina powder, 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.
