PROCESS AND SOLUTION FOR STABILIZING FERROSILICON

The aq. soln. suitable for ferrosilicon grist treatment comprises (g/l): potassium chlorate (50-150) potassium permanganate (0.1-2) potassium or sodium hydroxide (1-10). The ferrosilicon grist, wetted by the soln. at 15-30 deg.C, is then stabilised by heating and stirring at 400-500 deg.C, which ren...

Zusammenfassung:	The aq. soln. suitable for ferrosilicon grist treatment comprises (g/l): potassium chlorate (50-150) potassium permanganate (0.1-2) potassium or sodium hydroxide (1-10). The ferrosilicon grist, wetted by the soln. at 15-30 deg.C, is then stabilised by heating and stirring at 400-500 deg.C, which renders it suitable for mfr. of weld materials.
