<p>The composition consists of calcium chloride, ammonium potassium chloride, potassium and/or ammonium nitrate and water, the total quantity of water exhibiting a molar deficit of 1 to 12 % in relation to the quantity of water necessary for crystallising all the calcium chloride in the form of hexahydrate. The composition is produced by first of all making an aqueous solution of potassium chloride, of ammonium chloride and of potassium and/or ammonium nitrate, in which the calcium chloride is subsequently incorporated. <IMAGE></p> |
