摘要：we make a material loading base of the silica glass is used as a substitute forthe quartz crystal powder with an amorphous silica powder having a surface area (bet j.amer. chem. soc. 1938, 60, 84) of at least 10 m2g 1, and by reducing the surface area betby at least a factor of 10.the amorphous starting material may be formed by, for
example, silica fume, or be produced by hydrolysis of silicon tetrachloride with water, andthe reduction of the surface area of bet can be obtained by heat treatment at hightemperature (for example sup\érie ure to 2000f) in air or in an atmospherecontaining oxygen and halogen.helium or hydrogen.
