Annotatsiya

The possibility of obtaining highly dispersed powders of amorphous silicon dioxide from technogenic metallurgical wastes, which are dump slags of copper-smelting production and dustlike waste of the production of silicon and ferrosilicon (microsilica), is shown. A fairly simple and economical synthesis method is described using one reagent (ammonium fluoride (bifluoride)) at low temperatures (up to 400°C). The synthesized silica dioxide has a high degree of purity (~99.96%) and is amorphous, which are confirmed by spectrometry and X-ray phase analysis data. By laser correlation spectroscopy, it has been shown that the particle size distribution in an aqueous medium is bi- and trimodal; the particle diameter is predominantly 1300 and 5500 nm, and aggregate sizes of 130−250 nm are also present. The effective diameter of the silica particles decreases with increasing in ultrasonic treatment time.
