MISCH METAL Chemical Properties,Usage,Production

Chemical Properties

Grey trapezoid pieces

Uses

Lighter flints, ferrous and nonferrous alloys,cast iron, aluminum, nickel, magnesium and copperalloys, getter in vacuum tubes, magnetic alloys.

Uses

Misch Metal is used as dope for non-ferrous metal, such as aluminum (Al), iron-chrome-aluminum (Fe-Cr-Al), et al. This is to increase the operating life of Fe-Cr-Al heating devices. It is also used to manufacture flints in cigarette lighters.

Definition

The primary commercial form ofmixed rare-earth metals (95%) prepared by theelectrolysis of fused rare earth chloride mixture,d approximately 6.67, mp approximately 648C.Form: waffle-like plates weighing 40–60 lb packedin oiled paper, immersed in oil, or coated with vinylpaint.

Definition

A pyrophoric alloy of cerium and other lanthanoids, used in lighter flints.

Definition

An alloy of cerium(50%), lanthanum (25%), neodymium(18%), praseodymium (5%), and otherrare earths. It is used alloyed withiron (up to 30%) in lighter flints, andin small quantities to improve themalleability of iron. It is also addedto copper alloys to make themharder, to aluminium alloys to makethem stronger, to magnesium alloysto reduce creep, and to nickel alloysto reduce oxidation.

Hazard

Flammable, dangerous fire risk.
