摘要: A closed gas-cell cellular material is formed by heat treating a hydrosilicate, especially perlite, at low temperature and then in the form of grains grain size 5 to 8000 micrometers, feeding these through space 800° C. 2000° for short residence time uniform load 0.1 500 kg/h. Then are subjected thermal shock connector directly feed spacing heated 1,000° 3,500° The density granular thus produced 0.12 27 g/cm 3 weight per volume thereof 0.01 1 kg/liter.
