The most important indexes of refractory ceramic fiber are fiber diameter and thermal stability. Ceramic industry is commonly used in A2O3, SiO2 fiber, according to the content of A2O3 is divided into different range of use, also in which the introduction of Cr2O3 material to improve its fire resistance and oxidation resistance characteristics. Generally high content of alumina, iron oxide and other impurities low content of fiber products are pure white, the introduction of Ti lanot ti oksido ti kromio ket duyaw ti gatas. Ti promedio a diametro dagiti seramiko a lanot ket 2-4 Microns..
Fiber fine density is small, low thermal conductivity of the use of high temperature. If the fiber is coarse and dense, the effect is not ideal. The thermal stability index of fiber is more important. The linear shrinkage range of A2O3-SO2 fiber products at 1260℃is between 0.35-0.88%. The shrinkage also directly affects the thermal stability.
Gapu ti nababa a termal a konduktibidad, nababa a densidad ken nalag-an a dagsen ti seramiko a lanot a tabla, ti asero a kuadro a mangsuporta nga estruktura ket naadaptar iti disenio ken panagbangon ti urno, isu a ti panagrang-ay ti seramiko nga urno ket simrek iti panawen ti "nalawag a urno"..
Ceramic fiber board has small heat storage capacity and can adapt to rapid heating and cooling firing methods. Fiber is flexible and can be processed into products with grooves or openings, and has good resistance to mechanical vibration and impact, chemical stability is also good, these advantages for the development of new kiln, and extend to the development of ceramic technology, industry has an important role in promoting.
