Production Method of Scandium Aluminum Alloy Al-Sc Alloy  :

Atomization method: Atomization is a standard method for producing aluminum-scandium alloy powder. The technique is to atomize the molten liquid metal of aluminum and scandium into fine particles through high-pressure gas and then obtain the aluminum-scandium alloy powder during cooling and solidification. The atomization method can get the aluminum-scandium alloy powder with uniform composition and fine particle size, but the production cost is high.

Mechanical alloying method: The automated alloying way is mixing aluminum and scandium metal powder with high-energy ball milling and preparing aluminum-scandium alloy powder. In the ball milling process, aluminum and scandium metal powder continuously collide, and friction in the ball mill gradually forms the aluminum-scandium alloy powder. The mechanical alloying method can prepare Al-scandium alloy powder with uniform composition and fine particle size. Still, the production cycle is long and high-energy ball milling equipment is needed.

Chemical method: The chemical method converts aluminum and scandium compounds into aluminum-scandium alloy powder by chemical reaction. For example, the chlorides or oxides of aluminum and scandium are reacted with a reducing agent (such as hydrogen) to synthesize an aluminum-scandium alloy powder at high temperatures. The aluminum scandium alloy powder with uniform composition and fine particle size can be obtained by chemical method, but chemical reagents and high-temperature equipment are needed.

Electrolysis: Electrolysis is a method of preparing aluminum-scandium alloy powder by electrolyzing a salt solution of aluminum and scandium. During the electrolysis process, the cations of aluminum and scandium precipitate on the cathode and form an aluminum-scandium alloy powder. The electrolysis method can prepare aluminum-scandium alloy powder with uniform composition and fine particle size. Still, electrolytic equipment and salt solutions with high water quality requirements are required.
