摘要

The new-typed MLI comprised of alumina silicate fiber-papers, high temperature adhesive, hydrophobic silica aerogels granules and potassium hexatitanate (K2Ti6O13) whisker was prepared by felting process. The two samples by adding aerogels and K2Ti 6O13 whisker respectively were heat treatment for 100 h and 100 times at intervals of 1 h at 800 °C and 1000 °C. The microstructure, phase transfer and thermal conductivity of the two kinds of samples were characterized by SEM, XRD and calorimeter determination. These MLI samples took on less mass loss. The serious sinter of adhesive layers and decomposition of whiskers resulted in thermal conductivity increase.
