FIELD: mineral fibers. ^ SUBSTANCE: invention provides composite material, in particular material comprising soluble salt fibers bound with a binder, which can be used in manufacture of a variety of industrial and domestic ware resistant to temperatures exceeding 800. More specifically, material includes silicate-containing fiber and colloidal silica as binding agent. Silicate-containing fiber is composed of alkali-earth metal silicate fibers. Any of binding agent or filler contains small quantities of aluminum so that composite material contains at least 1 wt % aluminum (calculated for Al2O3). Contents of sodium and boron in material are also specified. ^ EFFECT: improved performance characteristics of materials at temperatures above 1200. ^ 25 cl, 8 tbl |
