The loop of wire at the tip may be made of platinum, tungsten or nichrome, the latter being inferior but less expensive.
22.
The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome, and stainless steel.
23.
In modern aluminum silvering, a sheet of glass is placed in a vacuum chamber with electrically heated nichrome coils that can evaporate aluminum.

carry out investigation of the relationship between lenght of a metallic conductor e . g nichrome wire and its resistance Preceding talk)
25.
In a toaster, by contrast, the nichrome resistance wire is directly exposed to the toast, for faster and more efficient heating.
26.
Usually a bomb-type calorimeter is started with a nichrome wire and a bit of thread if the sample will combust on its own.
27.
The temperature of the Nichrome wire and the cartridge heater were controlled by thermostats wired with thermocouples that were placed inside its body and tail.
28.
Mica sheets are used to provide structure for heating wire ( such as in Kanthal or Nichrome ) in heating elements and can withstand up to.
29.
Nichrome wire is also sometimes used . or melamine foam ( used in " eraser " cleaning sponges ) as a support have also been suggested.
30.
There are several heating technologies employed including copper wire, nichrome wire, metal " mesh'systems, carbon-embedded fabric and carbon fibers.
