| Zusammenfassung: | An insulating refractory material is made up of silicon material powder (10-85wt.%), alkaline catalyst (8-86 wt.%) and foaming agent (4-7wt.%) through chemical reaction between alkaline catalyst and part of silicon material powder, compounding rest of silicon material powder with resultant compound to obtain intermediate, and puffing under the condition of a certain temp. pressure and time to obtain Si-Si/gas composite material. Its advantages are the characteristics of inorganic material, low energy consumption, and simple making technology. |
