調製方法 · 1 件

製造方法Sodium-Potassium Alloy can be prepared by mixing 1 part Sodium and 5 parts Potassium (by weight) in refluxing xylene until melted. The melt is then carefully mixed with a glass stirring rod, keeping the alloy in one large globule. Upon cooling to room temperature, the alloy will remain liquid and can easily be transferred via a glass pipet.[1]
