uses.
Answers
Explanation:
An alloy is a solid or solution of two or more elements in a metallic matrix. It can either be a partial solid solution or a complete solid solution. Alloys are usually found to posses different physical properties than those of the component elements.
An important alloy of lanthanoids is Mischmetal. It contains lanthanoids (4-95%), iron (5%) and traces of S,C,Si,Ca and Al
Uses
(1) Mischmetal is used in cigarettes and gas lighters
(2) It is used in flame throwing tanks
(3) It is used in flame bullets and shills.
