Cigarette lighter

Cerium is a component of misch metal, which is extensively used in the manufacture of pyrophoric alloys for cigarette lighters. While cerium is not radioactive, the impure commercial grade may contain traces of thorium, which is radioactive. The oxide is an important constituent of incandescent gas mantles and is emerging as a hydrocarbon catalyst in self cleaning ovens. In this application it can be incorporated into oven walls to prevent the collection of cooking residues.

Isobutane is used in cigarette lighters and camp stoves as a fuel. It is easily liquefied under pressure, and the liquid becomes a gas immediately when the pressure is released. It is also used as a propellant in hairsprays and spray breath fresheners.

The battery life in some laptop computers is a consideration. Some laptop batteries may last long enough to perform calibration and application some may not. Additionally, there may be unforeseen circumstances that may require longer access to the laptop or that may cause premature battery failure. In order to ensure that data are not lost, a source of backup power, such as a spare battery or an adapter that plugs into the vehicle cigarette lighter, should be available. 

It is the usual practice on plants handling flammable materials to control the entry on to the site of obvious sources of ignition such as matches, cigarette lighters and battery-operated... 

The burglar trips and breaks his flashlight and also a large bottle of methanol that spills into a holding tank of 1.8 m diameter. He then uses a cigarette lighter to see. Use property data from the tables in Chapter 6 the gas specific heat is constant at 1.2 J/g K, the density for the gas in the room can be considered constant at 1.18 kg/m3 and the heat transfer coefficient at the methanol surface is 15 W/m2 K. 

Acetals are used for cigarette lighters thanks to their imperviousness to butane.

A commercial mixture of several of the rare-earth elements is called didymium (Di). It is neither an element nor a compound, but is used to name the mixture of oxides and salts of most of the rare-earth elements that are extracted from the ore monazite. Another unique substance, called misch metal, is an alloy of iron and several rare-earth elements (La, Ce, and Pr). This mixture is pyrophoric, which means it sparks when scratched. This is why it is used for cigarette-lighter flints. 

The prices of lanthanide elements are somewhat reasonable and are less than gold per kilogram. (Gold is about 1,800 per kg.) Cesium (Ce), which is relatively common, is often alloyed with La, Nd, and Pr and iron to form misch metal. This alloy has several uses based on its unique ability to spark when scratched. The most common use is as flints for cigarette lighters. 

It is used to manufacture safety goggles that filter out strong yellow light (used in welding, for example). Misch metal uses about 5% Pr in the manufacture of cigarette lighter flints. 

Platinum metal and its alloys have numerous applications. As a precious metal it is used extensively in jewelry. Other important applications include construction of laboratory crucibles and high temperature electric furnaces in instruments as thermocouple elements as wire for electrical contacts as electrodes in dentistry in cigarette lighters and for coating missile and jet engine parts. 

An interesting stage in the development of primer mixes was the use of pyrophoric metal alloys, first patented in 1936 and improved in 1964. These rare earth alloys, as used in cigarette lighter flints, give a shower of sparks when lightly scraped. A typical pyrophoric alloy is misch metal, which has the following approximate composition cerium 50%, lanthanum 40%, other rare earth elements 3%, and iron 7%.
