PCT No. PCT/EP97/02810 Sec. 371 Date Dec. 4, 1998 Sec. 102(e) Date Dec. 4, 1998 PCT Filed May 30, 1997 PCT Pub. No. WO97/47703 PCT Pub. Date Dec. 18, 1997The deicing composition described consists essentially of a) from 87 to 99.45% by weight of an alkali metal acetate or an alkali metal formate or a mixture thereof, b) from 0.5 to 10% by weight of an alkali metal silicate, and c) from 0.05 to 3% by weight of an alkali metal phosphate. It can be employed in solid form (powder, granules and the like) or in the form of an aqueous solution. It ensures a short thaw time and corrosion protection, especially with regard to magnesium.
