1.       Common Preparation Methods

Aluminum Lanthanum Cerium Master Alloy is typically prepared by vacuum induction melting or argon-protected melting techniques. The process begins by melting high-purity aluminum in a graphite or ceramic crucible under an inert atmosphere to prevent oxidation. Once the aluminum is molten (typically at around 700–800°C), lanthanum and cerium metals are carefully added in controlled amounts. This allows for uniform dissolution and incorporation of lanthanum and cerium into the aluminum matrix. Stirring is usually employed to ensure homogeneity. After alloying, the melt is cast into molds or ingots and allowed to solidify under controlled cooling conditions to minimize segregation. The resulting master alloy is then used to modify aluminum alloys in subsequent processes.
