The characteristics for a1umina- silicate fibre and K2Ti6O13 whiskers and SiO2 Aerogel are discussed in this paper. Several types of heat insulation materials with great prospect are suggested.

Polymer reinforced rapidly-dried sol silicate and fibre reinforced rapidly-dried sol silicate from oversea were introduced.

By deep Processing of kaolin, clay of jiaobao mineral, mineral wool fibre of aluminum silicate, a new kind of energy-saving material, can be obtained.
