Mica is actually a group of minerals mined around the world, but with notable deposits in Africa and Russia.
It has a number of interesting properties making it useful in a variety of specialized applications. Sheet mica has long been used in the electronic and electrical industries because of its combination of electrical, thermal insulating properties and its mechanical properties. Mechanically, it can be shaped, cut, drilled and the natural layered structure allows sheets to be created. It is a good electrical insulator at the same time as being a good thermal conductor which is an uncommon combination.
In an electric iron, its mechanical properties and thermal properties are decisive in why it is employed. Plastic would melt, or a metal conduct too much electricity and most other minerals would be brittle or difficult to shape as needed.
Because Mica is very good at conduting heat AND it won't melt under high heat

What is the difference between wood and mica?
Wood is an organic material of vegetal origin. Mica is an inorganic mineral.
What type of rock has thin flat sheets with nonmetallic material in it?
mica
Why the demand for mica has decreased?
In recent years, substitutes like plastics and synthetic material which are more effective and cheaper than mica have been found
What is the difference between mica schist and adventurine?
Mica schist is primarily composed of mica, whereas aventurine - note the spelling- is composed of quartz with abundant inclusions of mica. This makes for a relatively hard, tough and attractive material that can be polished into jewelry and many other items.
What would happen if lightning rod was made of an insulating material rather then of conducting material?
The electicity would create a black hole and destroy the universe
Is the material mica a poor conductor of heat?
mica is a plastice, so it is a poor conductor of heat and electricity. Mica is a mineral, not a plastic. But you're correct about its insulating properties.
Is Micah a word in french?
No, but mica is a word in French (it means mica in English, as in the material).
What type of substance would you use as as insulating material for a hot mitt?
Silicon is a type of substance you can use as a insulating material for a hot mitt.
Which material would be a poor conductor of electricity?
An insulating material such as rubber.
Give the example mesomorphous material?
mica
What is the difference between wood and mica?
Wood is an organic material of vegetal origin. Mica is an inorganic mineral.
For an insulating material dielectric strength and dielectric loss should be respectively?

Insulating material used in spark plug is?
Ceramic
For an insulating material dielectric strength and dielectric loss should be respectively high or low?
For an insulating material dielectric strength and dielectric loss should be respectively high or low
What is the insulating material beneath mammals skin called?
fat
Best dielectric material for corona discharge?
Mica sheet
What does insulating mean?
An insulating material is one that doesn't let something through easily. The "something" is usually either electricity, or heat.
