In recent years, as the extending of the prospects of ceramic fiber wool products. That has been widely used in the various kinds of furnaces. Meanwhile, ceramic fiber products also show its excellent energy-saving efficiency due to the advantages of good thermal insulation characteristic, low thermal conductivity etc.

1)Type & Characteristic.

The most important index for ceramic fiber is fiber diameter and thermal stability. Alumina silicate fiber is widely used in ceramic industry. According to the different content of AI2O3, the working temperature is also different. Meanwhile, people adding Cr2O3 to enhance the characteristic of refractory and oxidation resistance. Generally, the surface of the ceramic fiber products with high content of aluminium oxide and low content of the impurity such as iron oxide looks whiter than others. The average diameter of ceramic fiber products is 24um. The thinner of fiber diameter, the higher of the working temperature. The index of the thermal conductivity is more important. In addition, the permanent liner change on heating of alumina silicate fiber blanket is between 3588% in 1260°C. That was also affect the thermal conductivity.
