## Abstract A novel procedure is presented for precipitation of highly dispersed silica from sodium metasilicate solution using sodium hydrogencarbonate. In the course of silica precipitation, hydrophobicity‐inducing agents were introduced to the reactor, including derivatives of saturated and unsa
## Abstract Studies were conducted on the production of highly dispersed silicas using the technique of precipitation from solutions of sodium metasilicate and ammonium chloride. Parameters of the precipitation process were optimised in order to obtain highly dispersed as well as uniform and stable
The phase analysis of cryolite (Na 3 AlF 6 ) and sodium metasilicate (Na 2 SiO 3 ) was performed by thermal analysis. The eutectic system with a region of two immiscible substances at a concentration of Na 2 SiO 3 between 42.8 and 46.3 mol-% was identified and the eutectic temperature determined to
