Method of treating a blanket of ceramic fibres

摘要: A method of treating a blanket ceramic fibers containing 40 to 65% by weight alumina and 35 60% silica, which occupy total at least 95% weight, while the balance is other metal oxides, heat treated temperature 950°C 1100 °C, whereby fine crystals are formed in fibers, having thickness 6 50 mm. The compressed between pair presses therebetween clearance equal 80% thickness, it passed through roll speed not more than 500 cm per minute.
