Many heating elements use Nichrome 80/20 (80% nickel, 20% chromium). It is an ideal material because of its relatively high resistance.
When heated for the first time it forms a protective coating made of of chromium oxide, beneath which the heating element cannot oxidize.
The oxide coating prevents the wire inside from burning away or breaking, even if submerged in water, such as inside an electric kettle or large water heater.
Usually the element is well insulated and fully embedded into an outer copper housing which is chrome plated to help delay corrosion from the surrounding water which it heats.
If you look inside many electric kettles made since 1991 the heating element is not immediately visible because it is bonded onto the underside (i.e. the dry side) of the internal metal base plate. Such hidden elements work very well but have the disadvantage that, when an element burns out it cannot be replaced, so a new kettle has to be bought. However it is still a good system because the parts and labor costs for replacing one of the old types of replaceble heating element are much more than the cost of buying a new kettle.

Which materials are used in the manufacturing of standard resistors and heating materials?
Manganin used for standard materials...
What apparatus apart from a bunson burner is used for heating elements?
Aside from the Bunsen burner for heating elements alcohol lamp could be of good use too.
Do quartz toaster heating elements have a non-stick coating?
The quartz glass used in heating elements is used because it's transparent to infrared wavelengths of light. The glass has no coating whatsoever.
What is considered an open fire?
An "open flame" refers to flame, usually used as a heating source, that is directly exposed to the outside elements, or often the object to be heated. Examples would include a Bunsen burner, a bonfire, or in some cases grills. The opposite would include heating elements that do not directly openly expose the flame, such as old stoves or heating elements.
What are the things that heat up your toast in the toaster called?
They are called heating elements.
Which materials are used in the manufacturing of standard resistors and heating materials?
Manganin used for standard materials...
What is crucible used for?
A crucible is used for heating, melting or calcination of materials.
Are industrial ceramics good electricity conductors?
Generally ceramics are insulators. Some exceptions: silicon carbide, molybdenum disilicide, zirconium dioxide - these materials are largely used as heating elements.

Aside from the Bunsen burner for heating elements alcohol lamp could be of good use too.
Do quartz toaster heating elements have a non-stick coating?
The quartz glass used in heating elements is used because it's transparent to infrared wavelengths of light. The glass has no coating whatsoever.
What is dielectric heating?
Dielectric heating is a type of heating used in engineering. Insulated materials are heated and then put over an electric field that changes quickly. It is usually used for making plastics and rubber.
What mineral material is used as an insulator in electrical equipment?
Magnesium oxide is used in heating elements to isolate the inside heating wire from the elements outside sheath. This same material is used in Pyrotenax mineral insulated cables as an insulation medium.
What is the term used for living material?
THe term used is biotic elements nonliving organisms/materials are abiotic elements
What is the most significant use for tungsten?
In general Tungsten is used in heating elements. Lightbulbs and Oven elements are a common use.
What group of rock forming minerals are used as dielectrics in heating elements etc?
The micas are used as dielectrics.
What is the name of the method used when heating or boiling a mixture to recover the solid elements?
Distillation
What type of materials is an immersian heater used for?
The materials in a immerisian heater are used for making the heating element heat in water. Without them they couldn't be a chance for the heat to last.
