In the selection of aluminum silicate fiberboard, not only to test the composition of Al2O3, but also to strictly control the content of other impurities. Such impurities are low melting point oxides, and excessive low melting point oxides will reduce the co-melting point of aluminum silicate fiber materials. If the impurity content other than Al2O3 and SiO2 reaches more than 3.5%, then the ratio is controlled within 1%, which will reduce the actual use temperature of aluminum silicate fiberboard by nearly 100℃.
