The influence of cationic impurities in silica on its crystallization and point of zero charge.


The influence of the heat treatment on the crystal structure change of five (two laboratory prepared and three commercial) silica powders were investigated. Silicas were heat treated in the temperature range from 150 to 1300 degrees C in air. Also, the influence of the washing procedure with 0.01 mol/L HCl in order to desorb cations present as impurities in… (More)
