Examples
preparation example 1
[0103] An aluminum source for electrolytic preparation of aluminum alloys, prepared by the following method:
[0104] Mixed with anhydrous AlCl with a water content of 0.5% 3 12.1 mol and 0.5 mol of NaCl with a water content of 1.5% were used to obtain an aluminum-containing mixture, and the obtained aluminum-containing mixture was heated to 105° C., kept for 30 minutes, and cooled to room temperature to obtain 1# aluminum source. The molar ratio of aluminum element to sodium element in 1# aluminum source is 24.0.
preparation example 2
[0106] An aluminum source for the electrolytic preparation of aluminum alloys, the difference from Preparation Example 1 is that the aluminum-containing mixture is heated to 108.7°C, and liquid begins to appear, without heat preservation, and then cooled to room temperature to obtain 2# aluminum source . The molar ratio of aluminum element to sodium element in 2# aluminum source is 24.0.
preparation example 3
[0108] An aluminum source for electrolytic preparation of aluminum alloy, the difference from Preparation Example 1 is that the aluminum-containing mixture is heated to 108.7°C, kept for 2 minutes, and then cooled to room temperature to obtain 3# aluminum source. The molar ratio of aluminum element to sodium element in 3# aluminum source is 24.0.
